Question

50 Points! Find x and explain how you did? Will give 50 points!

Answer 1

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

$\\ \rm\hookrightarrow cosx=\dfrac{10}{20}$

$\\ \rm\hookrightarrow cosx=\dfrac{1}{2}$

$\\ \rm\hookrightarrow x=cos^{-1}\left(\dfrac{1}{2}\right)$

$\\ \rm\hookrightarrow x=\dfrac{\pi}{3}$

Answer 2

I believe the angle is 60°
