Answer:

m∠A ≈ 39.865°

Step-by-step explanation:

C² = 16² + 15² - 2 × 16 × 15 × cos (97°)

=> C = 23.22708085

sin (97°)/23.22708085 = sin A/15

=> sin A = sin (97°) × 15/23.22708085

=> A = $sin^{-1}$ (sin (97°) × 15/23.22708085)

=> A ≈ 39.865

Hi.

First, I am going to give you some definitions.This will help you do the problems.

-Complementary angles have a combined sum of 90.

- Supplementary angles have a combined sum of 180.

10. 40+50=90- so YES.

12. 159+20= 179.-so NO.

Make sure you learn the definitions properly next time!

A list of 8 numbers has a mean of 6. work out the total of the numbers.

VARVARA [1.3K]

Answer:

Step-by-step explanation:

The mean of a number is the sum of all the numbers divided by how many numbers there are. We can set up this formula: $mean = \frac{sum}{amountnumbers}$ .

When we plug our values into this equation, we get: $6 = \frac{sum}{8}$ . Solving this equation gets us sum = 6 * 8 = 48
