45 Pts!

Answer 1

Step-by-step explanation:

no calculator req

cos 60 is 0.5

so cos inverse of 0.5 os 60°

Answer 2

$\\ \tt\hookrightarrow cos^{-1}(0.5)$

$\\ \tt\hookrightarrow cos^{-1}\left(\dfrac{1}{2}\right)$

$\\ \tt\hookrightarrow 60°$

Fact about cosine(cos)

$\\ \tt\hookrightarrow cos\theta=\dfrac{Base}{Hypotenuse}$
