Question

A right triangle is shown.Which angle measure is the closest to x ?

Answer 1

To determine tha angle we need to notice that we know the adjacent leg and the hypotenuse. Then we can use the function:

`\cos x=\frac{\text{opp}}{\text{hyp}}`

Plugging the values we have and solving for x we have:

`\begin{gathered} \cos x=(20)/(24) \\ x=\cos ^(-1)((20)/(24)) \\ x=33.6 \end{gathered}`

Therefore x=33.6°.
