Question

The complementary angles are in the ratio 2.7. Find the measure of them.
​

Answer 1

lets the angles be 2x and 7x

so.2x+7x=90

9x=90

x=90/9=10

so the angles are

2x=2x10=20°

7x=7x10=70°

Answer 2

Answer:

Let the ratio be 2x and 7x

Complementary angle means 90°

ATQ,

2x+7x=90°

9x=90°

x=90/9

x=10°

So,

2x=2×10=20°

7x=7×10=70°

hope it will help you ✌️✌️
