Question

In a linear pair of angles , one angle is one fifth of other . The measure of this angle is..​

Answer 1

Answer:

let the fitst angle be x.

And,the second angle be1/5 x.

Now,we have

1/5x+x=180°

or,6x/5=180°

or,x=(180°×5)÷6

or,x=150°

Therefore, the measure of the angle=1/5×150°

=30°

And,x=150°
