Answer:
1. b/c 4. c/b
2. a/c 5. c/a
3. b/a 6. a/b
Step-by-step explanation:
sin theta = opposite/hypotenuse = b/c
cos theta = adjacent/hypotenuse = a/c
tan theta= opposite/adjacent = b/a
For the rest, you just flip it:
csc theta = c/b
sec theta = c/a
cot theta = a/b

Therefore, the correct answer is 26.I hope this helps! Let me know if you have any questions.
Solve the system of equations y = 2x^2 + x – 6 and y = 4
Step-by-step explanation:
Substitute y = 4 into the first equation:
[tex]4=2x^2+x-6[/tex]
Subtract 4 from both sides:
[tex]2x^2+x-10=0[/tex]
We can factor in order to find values of x.
Factor the equation:
[tex]2x^2+x-10=0[/tex]
Factors of 10 we'll use:
5 and 2.
[tex](2x+5)(x-2)=0[/tex]
Set the parentheses equal to 0 then find the values of x:
[tex](2x+5)=0[/tex]
[tex]x=-2\frac{1}{2}[/tex]
[tex](x-2)=0[/tex]
[tex]x=2[/tex]
[tex]x=2, \: or \: -2\frac{1}{2} .[/tex]

Ashton was born on the second Saturday in August many years ago. In that August, there were five Mondays and four Tuesdays. On what date was Ashton born?
Considering the situation described, it is found that Ashton was born on August 8.
What does the fact that there were five Mondays and four Tuesdays mean?It means that August 31 was on Monday, hence the same is valid for August 24, August 17, August 10 and August 3.
Hence, the first Saturday was August 1, and the second August 8.

solve for x
x - 1 2 (8 - x) = x + 3(4 - x) - x
Answer:
The correct answer is x = 32/9
Step-by-step explanation:
You must multiply the given numbers from left to right, resulting in:
x - 4 + x/2 = x + 12 - 3x - x
Then, by combining phrases on both sides that are similar, we get:
(3/2)x - 4 = -3x + 12
By adding 4 to both sides of the equation, it becomes:
(3/2)x = -3x + 16, or
3/2)x + (6/2)x = 16, which may be written as:
3x + 6x = 32, or 9x = 32
Therefore, the answer is x = 32/9

What is Isosceles Triangle ?An isosceles triangle has two equal sides regardless of the direction the apex (or peak) of the triangle points. Some useful information regarding isosceles triangles is as follows:
It has two parallel sides.It has two equal angles, which are known as the basis angles.A right isosceles triangle is one in which the third angle is 90 degrees.We have a Triangle.
Then, using Isosceles Triangle Theorem
Angles opposite an isosceles triangle's equal sides are also equal.
According to the isosceles triangle theorem, if two sides of a triangle are congruent, then the angles opposite the congruent sides are likewise congruent.
So, x= 42 degree.

please help, thank you very much to whoever helps.
Answer:
x = 20
B = 92°
C = 40°
Step-by-step explanation:
The sum of the interior angles of a triangle is 180°
⇒ A + B + C = 180°
⇒ 48 + (6x - 28) + 2x = 180
⇒ 48 + 6x - 28 + 2x = 180
⇒ 48 - 28 + 6x + 2x = 180
⇒ 20 + 8x = 180
⇒ 8x = 180 - 20
⇒ 8x = 160
⇒ x = 160 ÷ 8
⇒ x = 20
Now we have found x, simply substitute this into the expressions for angles B and C:
B = 6(20) - 28
= 120 - 28
= 92°
C = 2(20)
= 40°
Answer:
x = 20
m<B = 92
m<C = 40
(m<A = 48)
Step-by-step explanation:
triangles are 180 degrees
add up the sides
48 + (6x-28) + 2x
8x + 20 = 180
8x = 160
x = 20
put 20 where the x is for B and C
B.
6(20)-28 =
120 - 28 =
92
C.
2(20) =

A blood drive is being held at a local library. The coordinators of the drive wish to provide cylindrical cup of water to each participant. Each cup measures 5 inches tall with a radius
of 2 inches. How much water will each cup fold if filled to only 4 inches? Round to the nearest hundredth.
Answer:
50.24
Step-by-step explanation:
the formula to find a circle is radius times radius times pi, which equals 3.14. The radius is 2 so radius times radius would be 4. Now u times it by pi so 4 times 3.14 equals 12.56. Do this times ur hight wich is times 4 and u come up with 50 .24

Answer:
Step-by-step explanation:
Tan 70 = 16/x
x = 16/tan70
x = 5.824 to the nearest thousandth
tan 41 = 16 / (x + y)
tan 41 = 16 /(5.8235 + y)
tan41(5.8235 + y) = 16
5.8235 + y = 16/ tan41
y = (16/ tan41) - 5.8235
y = 12.582 to the nearest thousandth

A figure is comprised of 2 rectangles. The first rectangle has a length of 10.5 centimeters and width of 15.5 centimeters. The second rectangle has a length of 18 centimeters and width of 11.5 centimeters.
135 centimeters squared
207 centimeters squared
249 centimeters squared
279 centimeters squared
Answer:
249 centimeters squared
Step-by-step Explanation:
The area of the rectangle: l x w, where l is the length and w is the width.
= 15.5 x 18
= 279
Area of the smaller rectangle: l x w, where l is the length and w is the width.
= 4 x 7.5
= 30
We do not need this 30.
Area of the shaded region:
= 279 - 30
= 249 cm²

Answer:
the answer= y=5−x/2
Answer: [tex]y=-\frac{1}{2} x+5[/tex]
Step-by-step explanation:
We need to isolate y by itself
Step 1) Subtract 3x from both sides
[tex]3x+6y=30\\3x-3x+6y=30-3x\\6y=30-3x[/tex]
Step 2) Divide both sides by 6 to isolate y

Determine the solution(s) to f(x) = g(x) given the graph below.
Answer:
(-1,-3) and (1,-1)
Sometimes you give the solutions as just the x.
x = -1 and x = 1
Step-by-step explanation:
The two curvy pieces are f(x) and the straight line is g(x). The solutions are where the two graphs intersect. There are two points where this happens: (-1,-3) and (1,-1).
Sometimes your teacher, the text or the course just wants you to give the answer as the x where it happens. The graphs intersects where x=-1 and x=1

Answer:
so let's see buddy....
Step-by-step explanation:
look at that angle having 45, zed (Z) angles are equal, which means the bottom left inside the triangle is also 45°.
now sum of angles in a triangle is 180°...
so we add up all the angles and equal them to 180° but an angle is missing, let's name it Y°.
so...
96°+45°+Y°=180°
101°+Y°=180°
Y°=180°–101°
Y°=79°
to find x, sum of angles in a straight line is 90°
so we subtract 79 from 90
x°= 11
