Question

Find the measure of the indicated angle to the nearest degree

Answer 1

Answer: x=31°

Explanation:

To find the missing angle, we need to use SOHCAHTOA. We can eliminate sine and tangent because we aren't given the opposite side. Therefore, we use cosine.

`cos(x)=(48)/(56)` [use inverse cosine]

`x=cos^(-1)((48)/(56))`

`x=31`

Now, we know x=31°.
