find measure of two coplementry angles if they are in ratio 4:5.? explain it.

Let the given angles be 4x and 5xSince the given angles represent a pair of complementary angles, then4x + 5x = 90°⇒9x = 90°⇒x = 90°9 = 10°So, first angle = 4x = 4×10° = 40°second angle = 5x = 5×10° = 50°

Let the two complementary angles are 4x and 5x
Therefore
4x+5x=90
x=10

So the angles are...40 and 50

We all know that two complementary angles are 90 degree.
If they r in ration 4 and 5 so 4+5 is 9 so when we divide 90 by 9, we get 10 so 1 ratio is 10.....
4 ratio is 40 degree
5 ratio is 50 degree.....

Let the angles are x
The 4x+5x=90
9x=90
x=90/9
=10
So the answer is 40 and 50
