Answer:
a = 64°
b = 138.7°
Step-by-step explanation:
First, Let's find the measure a,
- 180° = 116° + a
- 180 - 116 = a
- a = 64°
______
Now,
- 90° + a + 82° + x + x + x = 360°
- 90+ 64 + 82 + 3x = 360°
- 236 + 3x = 360
- 3x = 124/ 3
- x = 41.3°
______
Now that we found out what x equals, let's find 'b'-
- b + x = 180°
- b + 41.3 = 180
- b = 180 - 41.3
- b = 138.7°

The answer for 8 should be c because it is a discount so you get to pay less.
It will be roughly 67.08 inches.
We can solve this using the Pythagorean Theorem, which is listed below.

In this equation, we use a and b as legs of a triangle and c is the hypotenuse. We can treat the length and height of the bookcase as legs and use this equation to solve for the diagonal (also known as the hypotenuse)



67.08 = c

3a: 15 is half of 30, so knowing that means the answer is 50%
3b. 3 is 1/4 of 12 because 3x4 is 12, meaning that 3 is 25% of 12.
3c. 6 over 10 as a decimal is 0.6. Which as a percent is 60%
4. Noah's method does work because 20% x 5 is equal to 100% of a number.
