Question

two complementary angles are in the ratio 4:5find the angle​

Answer 1

Answer:

Let the angle be x

then 4x+5x=90

9x=90

x=10

the angles are 40 and 50

Answer 2

Sum of complementary angles= 90 degrees

Ratio= 4:5

4x+5x= 90

9x= 90

x= 90/9

x=10

4x= 40

5x= 50

the angles are of measure 40 degrees and 50 degrees.
