Question

60° - Write the measure of supplementary angle of the given angle.

Answer 1

$\bold{ANSWER \:}$

As we know two angles whose sum is 180°makes a supplementary angle.

One angle = 60 ° (Given)

so another angle = x (let)

Their sum = (60 + x)°

Their sum is 180° as its it's supplementary angle

So Forming the equation as per the question we get

(60 + x)° = 180°

x° = (180-60)°

x° = 120°

Answer 2

Solution :

*****************************************
Two angles are said to be

supplementary if their sum is 180°

****************************************

Here ,

one angle ( x ) = 60°

Let second angle = y

x + y = 180°

=> y = 180° - x

=> y = 180° - 60°

=> y = 120°

Therefore ,

Supplementary angle of 60° = y = 120°
