Question

the ratio of complement and supplement of an angle is 2 ratio 5 find the angle​

Answer 1

Answer:

Step-by-step explanation:

Let the angle be x° .

Therefore, complement= (90-x)°

Supplement= (180-x)°

According to question

90-x/180-x=2/5

450-5x=360-2x (cross multiplication)

-3x= -90

3x = 90

x = 90/3

x = 30

Thus the angle is 30°.

Answer 2

Answer:

30
