Question

cosθ = 9/12
find θ

Answer 1

To find θ, we can use an inverse cosine function to find the angle whose cosine is equal to 9/12.

θ = arccos(9/12)

Using a calculator or a trigonometric table, we can find the value of θ:

θ ≈ 0.7227 radians or θ ≈ 41.41 degrees (rounded to two decimal places)
