Question

the angle which is one fifth of its complement is _​

Answer 1

Answer:

30 degrees

Step-by-step explanation:

Let the angle be a and its complement B.

a = 180-b

a+B = 180

a = 1/5 B is given.

So, 1/5 B + B = (1/5 + 1)B = (6/5) B = 180

So, B = 5/6 * 180 = 150

So, A = 150/5 = 30

Answer 2

Answer:

Step-by-step explanation:

let the angle be x

So compliment angle is 90-x

ATQ

x=1/5(90-x)

5x=90-x

6x=90

x=90/6

x=15
