Question

I need a step to step process pls :(

Answer 1

About 29.09 units

Explanation:

First, you need to find the measure of angle A. Since the interior angles of a triangle must add up to 180 degrees, A+63+101=180, and A is 16 degrees. Now, you can use the law of sines to find AB.

`(9)/(\sin 16)=(A)/(\sin 63) \\\\\\A=(9 \cdot \sin 63)/(\sin 16)\approx 29.09`

Hope this helps!
