Question

two complementary angles are in the ratio 7:8find the angles​

Answer 1

Step-by-step explanation:

let the angels be x

7x + 8x =180

15x =180

x=180÷15

x=12

7x = 7 × 12 = 84

8x= 12 × 8= 96

Answer 2

Answer :-

Given :-

• Ratio of complementary angles is 7 : 8.

To Find :-

• Angles

Solution :-

Let the angle be x

Complementary angle = 90 - x

According to the question :-

→ x : 90 - x = 7 : 8

→ x / 90 - x = 7 / 8

→ 8 ( x ) = 7 ( 90 - x )

→ 8x = 630 - 7x

→ 8x + 7x = 630

→ 15x = 630

→ x = 630 / 15

→ x = 42

Other angle = 90 - x

= 90 - 42

= 48

Angles = 42° and 48°
