Answer:
x = 30
y = 7
Step-by-step explanation:
The triangle given is an equilateral triangle.
Equilateral Triangle
A triangle that has same length of all sides of triangle. They have same congruent internal angles as well.
So, If length of one side = 7
Length of other two sides will also be same i,e 7
Length of 2nd side = 7
Length of 3rd side = 7
Now, finding angles and value of x
The one angle is 2x, so the other two angles will be also 2x (because all angles of equilateral triangle are same)
We know that sum of all sides of angles of triagle = 180
We can write: [tex]2x+2x+2x=180[/tex]
Solving the equation to find x
[tex]2x+2x+2x=180\\6x=180\\x=180/6\\x=30[/tex]
So, x = 30
Since y is not given in picture, I think it is length of other sides i.e y = 7

(In reference to my diagram.... my diagram is similar to the diagram in the question)
We know that diagonals of a square bisect each other at right angles.
In ΔBOC ,
•OB = OC (Diagonals of square bisect each other)
=> ∠OBC = ∠OCB = (7x + 3)° (∵ OB = OC)
• ∠BOC = 90° (Diagonals intersect at right angles)
Using angle sum property of triangle ,
∠OBC + ∠OCB + ∠BOC = 90°
[tex] = > 7x + 3 + 7x + 3 + 90 = 180[/tex]
[tex] = > 14x + 6 = 180 - 90 = 90[/tex]
[tex] = > 14x = 90 - 6 = 84[/tex]

Two shops sell the same phone. In both shops it is £196. One shop increases the price by 17.5%. The other shop increases the price by 22.5%. Calculate the difference between the new prices of the phone in the two shops.
Answers
Step-by-step explanation:
the 1st shop=196-(17.5/100×196)
=196-34.3
=161.7+196
=357.7
the 2nd shop=196-(22.5/100×196)
=196-44.1
=151.9+196
=347.9
so the difference between two shop is
357.7-347.9=9.8

Answer:
m∠C=28°, m∠A=62°, AC=34.1 units
Step-by-step explanation:
Given In ΔABC, m∠B = 90°, , and AB = 16 units. we have to find m∠A, m∠C, and AC.
As,
⇒
By angle sum property of triangle,
m∠A+m∠B+m∠C=180°
⇒ m∠A+90°+28°=180°
⇒ m∠A=62°
Now, we have to find the length of AC
⇒
The length of AC is 34.1 units
The area of a rectangular warehouse measures 4,288 square feet. The width of the warehouse is 64 feet long. Draw a model to represent the problem, and then solve for the length of the warehouse.
Answers
Answer:
67 feet
Step-by-step explanation:
Step one:
given
The area of a rectangular warehouse measures 4,288 square feet
The width of the warehouse is 64 feet long.
Required:
the length of the warehouse
Step two:
The expression for the area of a rectangle is

so, for the situation
4,288= L*64
solve for L
divide both sides by 64
L= 4,288/64
L=67 feet

What is the exact value of tan ( 5 pi/8 )
Answers
===================================================
Explanation:
Make sure your calculator is in radian mode. Use your calculator to find that tan(5pi/8) = -2.41421 which is approximate.
Since the value is negative, this means the answer is between choices C and D. You can use your calculator to compute those expressions given and you should find it matches with choice D.
----------------------
Further explanation:
We can apply the half angle identity for tangent like so
[tex]\tan\left(\frac{x}{2}\right) = \pm \sqrt{\frac{1-\cos(x)}{1+\cos(x)}}\\\\\\\tan\left(\frac{5\pi/4}{2}\right) = -\sqrt{\frac{1-\cos(5\pi/4)}{1+\cos(5\pi/4)}}\\\\\\\tan\left(\frac{5\pi}{8}\right) = -\sqrt{\frac{1-\left(-\frac{\sqrt{2}}{2}\right)}{1+\left(-\frac{\sqrt{2}}{2}\right)}}\\\\\\[/tex]
Simplifying further, we get
[tex]\tan\left(\frac{5\pi}{8}\right) = -\sqrt{\frac{1+\frac{\sqrt{2}}{2}}{1-\frac{\sqrt{2}}{2}}}\\\\\\\tan\left(\frac{5\pi}{8}\right) = -\sqrt{\frac{2+\sqrt{2}}{2-\sqrt{2}}}\\\\\\[/tex]

2x - 3x - 18 + -18 + 2x + 5x x= .....? A.X=4.5 B.X=0 C.X=6 D.X=-4.5 :) please help?
Answers
Answer:
-36+7x
Step-by-step explanation:
Answer:
x = 0
Step-by-step explanation:
First, simplify the equation by combining like terms on each side:
2x = 3x - 18 = -18 + 2x + 5x
-x - 18 = -18 + 7x
To solve the equation for x, the variable must be isolated on one side of the equal sign. Use the subtraction property of equality to subtract 7x from both sides. Then use the addition property of equality to add 18 to both sides:
-x - 18 - 7x = -18 + 7x - 7x
-8x - 18 = -18
-8x -18 + 18 = -18 + 18
-8x = 0
Finally, use the division property of equality to divide both sides by -8 and achieve the solution for x:
-8x/-8x = 0/-8
x = 0

Step-by-step explanation:
Given that :
Using Pythagoras rule :
Hypotenus = sqrt(Adjacent^2 + opposite^2)
From the attached picture :
x² = 87^2 - 63^2
x^2 = 7569 - 3969
X^2 = 3600
Take the square root of both sides :
X = sqrt(3600)
X = 60 feets
Hence, Katy and Tony are 60 feets apart

Answers
Answer:
40%
Step-by-step explanation:
The first step is to calculate the unit selling price
= total sales/number of units
= 200,000/50,000
= $4
The unit variable expense can be calculated as follows.
= total variable expense/number of units
= 120,000/50,000
= $2.4
The contribution margin per unit can be calculated as follows
=selling price per unit- variable cost.
= $4-$2.4
= $1.6
Therefore the contribution margin ratio can be calculated as follows.
= $1.6/$4
= 0.4×100
= 40%

An amusement park reduced the admission price to $15.50 per day, but now charges $1.50 per ride. Mark has $26 to spend on admission and rides. Write an algebraic equation to find how many rides Mark can ride in one day.
Answers
Answer:
15.50 + 1.50x ≤ 26
Step-by-step explanation:
Given that:
Total amount to spend = $26
Admission fee = $15.50
Charge per ride = $1.50
Number of rides Mike can take in a day:
Let number of rides can take In a day = x
[Admission fee + (charge per ride * number of rides)] less than equal to total amount
15.50 + 1.50x ≤ total amount
15.50 + 1.50x ≤ 26
1.50x ≤ 26 - 15.50
1.50x ≤ 10.50
Divide both sides by 1.50
x ≤ 10.50 / 1.50
x ≤ 7
Hence, number of rides per day = 7

What is the length of PR?

Answer:
The correct option is;

Step-by-step explanation:
In triangle ΔPQR the given parameters are;
The length of [tex]\overline {QP}[/tex] = 19.5 in.
The length of [tex]\overline {QR}[/tex] = 7.5 in.
In triangle ΔVWX, the given parameters are;
The length of [tex]\overline {WV}[/tex] = 13 in.
The length of [tex]\overline {WX}[/tex] = 5 in.
The length of [tex]\overline {VX}[/tex] = 7 in.
Given that we have;
[tex]\dfrac{\overline {QP}}{\overline {WV}} = \dfrac{19.5}{13} = 1.5 , \ \dfrac{\overline {QR}}{\overline {WX}} = \dfrac{7.5}{5} = 1.5[/tex]
The ratio of the corresponding sides of triangle ΔPQR and triangle ΔVWX are equal, therefore ΔPQR is similar to ΔVWX, from which we have for the corresponding sides, [tex]\overline {PR}[/tex] and [tex]\overline {VX}[/tex];
[tex]\dfrac{\overline {PR}}{\overline {WV}} = \dfrac{\overline {PR}}{\overline {7}} = 1.5[/tex]
∴ [tex]\overline {PR}[/tex] = 7 × 1.5 = 10.5
The length of [tex]\overline {PR}[/tex] = 10.5 inches
