Question

If angle X is equals to 30, angle Y is equals to 115 where angle A and angle X are the complementary angle Y and Angle B are supplementary then angle A + Angle B is

Answer 1

Answer:

x + a = 90 , 30 + a = 90 , a =90-30 , a =60

y + b = 180,115+ b = 180,b=180-115,b=65

a +b =,60 + 65 = 125
