Question

Find the measure of angle A.


32

57

59

No angle exists

Answer 1

\(\bf cos(\theta)=\cfrac{\textit{adjacent side}}{hypotenuse}\)

Answer 2

\(\bf cos(\theta)=\cfrac{\textit{adjacent side}}{hypotenuse}\implies cos(\theta)={\color{red}{ \square }}\quad \textit{taking }cos^{-1}\\ \quad \\

cos^{-1}[cos(\theta)]=cos^{-1}({\color{red}{ \square }})\implies \theta=cos^{-1}({\color{red}{ \square }})\)
