Question

Two complementary angles are in ratio 7:2. Find the angles.

Answer 1

Answer:

70° and 20°

Step-by-step explanation:

let the angles be, 7x and 2x

measure of complementary angles=90°

7x+2x=90°

9x=90°

x=90/9

x=10°

7x=70°

2x=20°

Answer 2

Step-by-step explanation:

complementary angles means sum of 2 angles is 90 degrees.

given ratio=7:2

term 1=7x

term2=2x

sum of 2 terms is 90°

so,

=7x+2x=90

=9x=90

=x=10

therefore the angles are 70 and 20
