Question

The measure of two angles are in ratio of 7:8 and they are complementary angle . What are their measures in degree

Answer 1

HLW FRIEND
Let two ratios be x:y=7:8
AND,If they are complementary then, there sum must be equal to 90 degree
SO,x+y=90
and 7+8=15
for x degree=7/15×90=42 degree
and 2nd measure is y=8/15×90=48 degree
THANK U☺

Answer 2

Let the angle be x,

Therefore,

7x+8x=180

15x=180

x=180/15

x=12

7x=7×12=84degree

8x=8×12=96 degree
