1.) Solve for length b.
The simpler method is to use the Pythagorean theorem. If , then this means that
.
Plug in the values:
-->
So this means that b is the square root of 72, which is 8.49
2.) Solve for ∠A.
Let's refer to the law of sines. If , then this means we can cross multiply. Since A is the value we are solving for, the equation should be written out like this:
-->
A is 39.52°
3.) Solve for ∠B.
This is the easiest one. The sum of all three angle measures in a triangle add up to 180°. We already know that one of the angles is a right angle and the other 39.52°.
39.52 + 90 = 129.52
180 - 129.52 = 50.48
∠B is 50.48°.
