tan 52 = 180/a; a = 180/tan 52
tan 43 = 180/b; b = 180/tan 43
you need to calculate, a-b = 180/tan 52 - 180/tan 43
substitute the value of tan thetas, and calculate it simply...
Subtract 8/10 from 4/10 but just the numerator (the top number) and you will get 4/10
$.75 bc 15 x 4 is 75 so that would make 75¢ or $.75
