Question

An angle is 77º. What is the measure of its supplement?

Answer 1

Answer:

Angles are measure of rotation, along with its direction of rotation. The supplement angle of 77° is 103°

How to find the supplement angle of an angle?

Supplement angle of an angle is such that sum of both of them comes as 180°

Thus, if an angle is of A°, then its supplementary angle is 180° - A°

For the given case, we let the first angle be of A° = 77°, then its supplementary angle with measure B° is:

Thus, The supplement angle of 77° is 103°
