Explanation:

Sorry I was'nt to explain step by step But I know the answer

Answer 2

No worries, here’s how i would do it.

To find the inverse cosine (cos⁻¹) of a value, you can use a calculator or a programming language that includes trigonometric functions. In this case, we want to find the angle whose cosine is 7/8.

cos⁻¹(7/8) = θ

Using a calculator or programming language:

θ ≈ 30.96°

Rounded to the nearest degree:

θ ≈ 31°

So, cos⁻¹(7/8) is approximately 31°.
