Question

Two complementary angles are in the ratio 7:2 what are their measures​

Answer 1

Answer:

Step-by-step explanation:

Angles whose sum is 90° are called supplementary angles .

Ratio of the angles = 2:7

So , let the angles be 2x and 7x .

Now , acc. to the question ,

2x + 7x = 90

=> 9x = 90

=> x = 10 .

2 × 10 = 20 ,

7 × 10 = 70 .

So , the two angles are , 20° and 70° .

Answer 2

Step-by-step explanation:

let the measure of angles is x.

7x+2x=90

9x=90

x=90/9

x=10

their measures are,

7x=7×10=70

2x=2×10=20
