Question

find the angles which is 1/5 of its complement​

Answer 1

The sum of an angle and its complement is always 90.

Let us say that the angle = x

Then, its complement = 5x

Now,

x + 5x = 90

6x = 90

x = 15

So, the angle which 1/5 of its complement = 15 degrees

Answer 2

Let the angle be,x.

then another angle =x/5

x+x/5=90 degree

6x=90*5

x=90* 5/6

x=75degree

so,

x/5=75/5=15 degree
