Angles A and B are complementary. Angle A is 63º . Find the measure of angle B.
a 87°
b 97°
C 27°
d 77

The answer is C. Since these two angles have to add up to 90 degrees and Angles is 63 degrees. Subtract 63 from 90 and you get 27. Angle B is 27 degrees.

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
