Question

What is the measure of supplementary angle of 2x0?
A)90-2x B)180-2x C)180+2x D)90+2x

Answer 1

Correct Question:

What is the measure of supplementary angle of 2x° ?

A) 90-2x

B) 180-2x

C) 180+2x

D) 90+2x

Answer :-

The measure of supplementary angle of 2x° is 180 - 2x.

[ Option. (B) ] is correct.

Step-by-step explanation:

To Find :-

• The measure of supplementary angle.

Solution:

Given,

⇒ One supplementary angle = 2x°

We know,

Supplementary angle = 180°,

Therefore,

⇒ 180 - 2x

THINGS TO REMEMBER :-

• The sum of two or more angles, which measures 180° is known as supplementary angle.
• The sum of two or more angles, which measures 90° is known as complementary angle.
