Question

two complementary angles are in the ratio 4:5. find the angels????????

Answer 1

Complementary angles= 90°
The ratio is 4:5
Let it be 4x,5x
Now, their sum =90°
4x+5x=90°
9x=90°
x=90/9=10
x= 10°
Measure of 1 angle = 4x=4*10=50°
Measure of 2 angles =5x= 5*10 = 50°
Angles are 40° and 50°

Hope this helps you friend
Thanks ✌️✌️

Answer 2

Let 4:5 be 4x and 5x respectively. As it is complementary angle it should be 90 degrees.

4x + 5x = 90

9x =90

X=90/9

X=10

4x= 4*10=40 degrees

5x=5*10=50 degrees
