Question

two complementry anglesare in ratio 4:5 then find the angle

Answer 1

Heya !!





Let two complementary angles are 4X and 5X.




As we know that , sum of two complementary angles is always equal to 90°.



So,




4X + 5X = 90




9X = 90



X = 10°.




First angle = 4X = 4 × 10 = 40°



And,



Second angle = 5X = 5 × 10 = 50°.

Answer 2

4x+5x=90°
9x=90

x=90/9
x=100


$0,,


4x=4*10=40

5x=5*10=50


that's all
