Question

Instructions: Find the measure of angle A associated with thefollowing ratios and round to the nearest degree.

Answer 1

Answer: We have to find the angle associated with the provided ratio:

$\cos(A)=0.2785$

The answer is as follows:

$\begin{gathered} \cos(A)=0.2785 \\ \\ A=\cos^{-1}(0.2785)=73.82929959 \\ \\ \\ A\approx74 \end{gathered}$

Therefore the answer is 74.
