Question

Find x. Round your answer to the nearest tenth of a degree.

Answer 1

~62.35°

Explanation:

To find the degree of an angle from side lengths, use reverse trigonometric function.

arcsin, arccos, arctan /
`sin^-1, cos^-1, tan^-1`

Because we have adjacent and opposite, lets use arctan.

Set up the equation.

`x = arctan(21)/(11)`

Use a calculator to solve.
