Given sin A = -.45 find angle A in degrees. Round your answer to the nearest hundredth

Question

anonymous · Answer

In order for you to be able to do this, you need to get A by itself. Is there a way to get A by itself and sin on the right side of the equal sign?

oops - i had a brainstorm then!!
the sine is negative in the 3rd and 4th segments  so there are 2 solutions in the range 0 to 360 degrees

use your calculator - look up sin-1 0.45 - it will give you an agle in first quadrant  ie between 0 and 90 degrees
 A will be 180 + x, or 360 - x
