**DrBob222**, Tuesday, December 18, 2012 at 10:11pmIf sin A = 0.5, doesn't that make A =- 30 degrees. That is >0 and <180 so it qualifies. Just punch in the other numbers on your calculator and read the angle A. See if it meets the criteria.

**DrBob222**, Tuesday, December 18, 2012 at 10:31pmThat - slipped in. Sin A = 0.5; A = 30 degrees and not -30 degrees.
