if the Vertical angle of an isosceles triangle is equal to the sum of the base angle find the size of each angle
​

Answer:

[tex]\displaystyle 5x + 6y = 72\:or\:y = -\frac{5}{6}x + 12[/tex]

Step-by-step explanation:

Perpendicular equations have OPPOCITE MULTIPLICATIVE INVERCE RATE OF CHANGES [SLOPES], so 1⅕ becomes −⅚, and we move forward with plugging the information into the Slope-Intercept formula:

[tex]\displaystyle -8 = -\frac{5}{6}[24] + b \hookrightarrow -8 = -20 + b; 12 = b \\ \\ \boxed{y = -\frac{5}{6}x + 12}[/tex]

To write this in Linear Standard Form, perfourm he following:

y = −⅚x + 12

+ ⅚x + ⅚x

___________

⅚x + y = 12 [We cannot leave the equation this way, so multiply the equation by the denominatour to eradicate the fraction.]

6[⅚x + y = 12]

[tex]\displaystyle \boxed{5x + 6y = 72}[/tex]

Answer:

c. 1 1/2 hours

Step-by-step explanation:

6 hours / 4 games = 1 1/2 hours per game

Another way to think of it:

1 hour = 60 minutes

6 hours = 6 hours x 60 minutes per hour = 360 minutes

360 minutes / 4 games = 90 minutes per game

90 minutes per game / 60 minutes per hour = 1.5 hours

1.5 hours is the same as 1 1/2 hours

So, the answer is c. 1 1/2 hours

Applying proportions, it is found that the discounted price of each console at store B is given by:

B. $210.80.

A proportion is a fraction of a total amount.

In this problem, at store B, 15 consoles sold for a total of $3,720, hence the price per console is of:

P = 3720/15 = $248.

A discount of 15% is applied, which means that the new price is 85% of the original price, hence:

P = 0.85 x 248 = $210.8.

Which means that option B is correct.

Answer:1) In Δ FGH,

FH=7 ft, FG=12 ft,

∠F=70 degrees

By "Law of cosines":

So,By applying Law of Sines , we get that

Hence, Option 'D' is correct.

2) In Δ XYZ,

XY=14, ∠Y=22°, and XZ=26

By using "Law of sines":

so, X = 147° , Y = 22° , Z = 11.6°

Answer:

Step-by-step explanation:

Answer: 6cm.

Step-by-step explanation:

Strategy 1 (in-head thinking)

300 divided by 50 would be 6, multiply 6 by 1 and get 6cm.

Strategy 2 (proportions)

First, set up a proportion.

We know that 1cm = 50km, so we put them on a fraction (whichever is denominator/numerator doesn’t affect the process)

However, we don’t know how much cm equals 300km, so we turn that into a variable, in this case x.

1cm       x cm

———   ———

50km  300km

To solve a proportion, go diagonal to where the variables have already been filled in. You can’t so 50km and x cm, as you don’t know x. You can do 300km however. To start, multiply 1 and 300, to which you get 300. Then, multiply 300 by the 50km and you’ll get x. That’ll equal to 6.

So in conclusion, your answer is 6.

Answer:

[tex]\tan(X)=\dfrac{77}{36}[/tex]

Step-by-step explanation:

First we need to find the length of side WX.

To do this, use Pythagoras' Theorem:  [tex]a^2+b^2=c^2[/tex]

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

[tex]\implies WX^2+77^2=85^2[/tex]

[tex]\implies WX^2=85^2-77^2[/tex]

[tex]\implies WX=\sqrt{85^2-77^2}[/tex]

[tex]\implies WX=36[/tex]

Now use the Tan trig ratio:

[tex]\tan(x)=\sf \dfrac{O}{A}[/tex]

where:

From inspection of the triangle,

Substituting these values into the tan trig formula:

[tex]\implies \tan(X)=\dfrac{77}{36}[/tex]

Therefore, the tangent of ∠X is [tex]\dfrac{77}{36}[/tex]

The angle of fire in the standard position will be B. 120°; 2 pi over 3 radians.

It should be noted that the image shows the shooting angles arrangements. Also, π = 180°.

In this case, the value of the angle will be:

= 12π/18

= (12 × 180) / 18

= 12 × 10

= 120°

Therefore. the angle of fire in the standard position will be B. 120°; 2 pi over 3 radians.

The pounds of food that Sand Hill Crane Elementary  needs to collect more in order to reach their goal is 1202 pounds.

The first step is to convert tons to pounds.

1 ton = 2000 pounds

2 tons x 2000 = 4000 pounds.

The second step is to subtract the pounds of food collected so far from the goal.

its curl is

[tex]\displaystyle \nabla\times\vec A = \left(\frac{\partial\left(2yz^4\right)}{\partial y} - \frac{\partial\left(-2x^2y\right)}{\partial z}\right) \, \vec\imath - \left(\frac{\partial\left(2yz^4\right)}{\partial x} - \frac{\partial\left(xz^3\right)}{\partial z}\right) \, \vec\jmath \\ ~~~~~~~~~~~~ + \left(\frac{\partial\left(-2x^2y\right)}{\partial x} - \frac{\partial\left(xz^3\right)}{\partial y}\right) \, \vec k[/tex]
