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 ✌️✌️
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
