Question

If one angle is ( 90 - x) degree, find the supplement angle

Answer 1

Answer:

Supplementary angles are 180

Step-by-step explanation:

90-x=180

X=180-90

X=90

Answer 2

The supplement of the angle ( 90 - x)°  is ( 90 + x )°.

Given: One angle is ( 90 - x) degree

To Find: The supplement angle

Solution:

• We know that, pair of angles are said to be supplementary angles if their summation is equal to 180°.
• Suppose A and B are supplementary angles, then

                       A + B = 180°

We are required to find the supplement of the angle  ( 90 - x )°.

So, let the supplement angle be 'y',

∴    y + (90 - x)° = 180°

⇒  y = 180° - 90° + x°

        = ( 90 + x )°

Hence, the supplement of the angle ( 90 - x)°  is ( 90 + x )°.
