Question

c) ZA and B are supplementary angles. If zB is five times ZA, find the measure of
both the angles.

​

Answer 1

Answer:

A = 73 B = 17

Step-by-step explanation:

if angles are complementary than they are found adjacent to each other in a right angle.

From above you can see that A+B=90 so I can add my two angles together and have it equal to 90

(5× +8 ) +(× +4)=90

5× + 8 + × + 4 =90

6× + 12 = 90

6× = 90 - 12

6× = 78

× = 13

So A = 5× + 8 = 5 (13) + 8 = 65 + 8 = 73

and B = × + 4 = 13 + 4 = 17

just make sure you are correct add your A and B together and they should equal to 90

ie A + B = 73 + 17 = 90
