Okay so here is the question
Each angle of A is between 0 degrees and 180 degrees. Which equations result in two different values for angle A ?
-sin A = .7071
-cos A = -.5
-sin A = .9269
-cos A = -.7071
-sin A = .8660
-cos A = -1
-sin A = 3/4
-cos A = 3/4
-cos A = -3/4
I would like how you got there as well ! thanks !
