Question

Find the missing side or angle.

Answer 1

A) 42.6

Explanation:

You should know SOH CAH TOA.

Where hypotenuse will be opposite the right angle

Opposite will the side across the angle

Adjacent will be the side next to the angle

Since we have an unknown on the hypotenuse and a known side on the adjacent we will use Cosine:
`cos\alpha =A/H`

`cos(62)=20/x\\ x=20/cos(62)\\ x=42.6`
