Question

Calculate the approximate degree measure of the angle, given the following expression: cos(y°) = -0.10 Round your answer to the nearest tenth.​

Answer 1

y ≈ 95.7°

Explanation:

To solve for the angle a trigonometric function is being used on, we have to use the inverse of the trigonometric function.

Inverse of tan(y°) = 4.12:

`tan^(-1)(-0.10) = y`

Next, I used a scientific calculator to find the angle measure of y. I recommend using the Desmos Scientific Calculator.

`95.7 = y`
