Find angle A if it is greater than or equal to 0 degrees and smaller than or equal to 180 degrees. round to the nearest tenth of a degree, if necessary.

a) sinA = 0.5

b) cosA = -0.5

e) cosA = 0.4561

g) sinA = 0.5736

PLEASE HELP WID THIS!!:( i tried so much! but im not getting it...

Thanks I greatly appreciate it sooo much!!:)

If 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.

That - slipped in. Sin A = 0.5; A = 30 degrees and not -30 degrees.
