Question

12. Two complementary angles are in the ratio 4:5. Find the angles.​

Answer 1

Answer:

4x + 5x = 90

9x = 90

x = 90/9

x= 10

Angles= 4×10=40

5×10=50

Answer 2

Answer:

The two angles are 40° and 50°

Step-by-step explanation:

Let the common multiple be x

the two angles are 4x and 5x

The complementary angles are angles which have the the sum of two angles 90°

So, 4x+5x=90°

9x=90°

x=10°

now first angle=4x=40°

second angle=5x=50°
