Question

If the supplement of an angle is 65. then find its complement.

Answer 1

Let Supplement of angle x is 65 We know that sum of supplementry angles is 90 == x+65=90 == x= 90-65= 25 Now complement of this angle vl be 180-x= 180-25= 155

Answer 2

Answer:

Given : the supplement of an angle is 65.

To Find: find its complement.

Solution:

Let the angle be x

Supplementary angles : A pair of angles whose sum is 180° is called supplementary angles

Supplement of x = 180°-x

We are given that  the supplement of an angle is 65.

So, $180^{\circ}-x=65^{\circ}$

$180^{\circ}-65^{\circ}=x$

$115^{\circ}=x$

So, the angle is 115°

Now Complementary angles : A pair of angles whose sum is 90° is called complementary angles

Since the angle 115°is greater than 90° so its complement cannot be determined
