Question

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

Answer 1

Step-by-step explanation:

let the ratios be x so 4x and 5x

we know the sum of complementary Angle is 90 so 4x + 5x = 90

9x = 90

x = 10

hence the angles are

4x = 4*10 = 40

5x = 5*10 = 50

Answer 2

let the angles be = 4x and 5x

then, 4x+5x= 90° ( Complementary angle is of 90°)

9x = 90°

x= 90/9

x= 10

so, the angles are:

4x = 4×10= 40°

5x = 5×10= 50°
