Answer 1

Explanation:

To find the missing measures of the angle, we will use the inverse functions of sine and cosine.

So, if sin θ = 0.866, the measure of the angle θ is equal to:

$\begin{gathered} \theta=\sin ^{-1}(0.866) \\ \theta=60 \end{gathered}$

And if cos θ = 0.906, then the measure of the angle θ is:

$\begin{gathered} \theta=\cos ^{-1}(0.906) \\ \theta=25 \end{gathered}$

Therefore, the complete table is:

Ratio Measure of the angle

tan θ = 1 45

sin θ = 0.866 60
