To solve a right triangle means to find the measure of all of its sides and angles.

3. Write a trig ratio to find the measure of angle A in the following triangle17 B C 15

4. How can we solve for A?
This doesn’t mean sin plus A or sin times A, so how do we get A by itself?

5. Use inverse trig function
This is 2nd -> sin in your calculator.
(Make sure your calculator is in degree mode first)
