Question

find the supplement of each of the following angles 3 by 5 of a right angles​

Answer 1

Answer:

180° - 54° = 126°

Step-by-step explanation:

Supplementary angles always add up to 180°....

Here, 1st angle is 3/5 of 90° = 54° (calculation will give out this result)

Therefore, let the unknown angle be 'x',

Equation: 180° = x + 54°

⇒ 180° - 54° = 126°.....

Hope you have understood the method...
