Question

at a road intersection, one angle formed is 63. what is the measure of the supplementary angle?

Explanation:

Step1: Recall supplementary angle definition

Supplementary angles sum to \(180^\circ\).

Step2: Calculate supplementary angle

Let the angle be \(x = 63^\circ\), its supplement \(y\) satisfies \(x + y = 180^\circ\). So \(y = 180^\circ - 63^\circ = 117^\circ\).

Answer:

\(117^\circ\)
