Question

two angles are supplementary. the first angle measures 25°. what is the measure of the second angle?

Explanation:

Step1: Recall supplementary angles definition

Supplementary angles sum to \(180^\circ\). Let the second angle be \(x\). So, \(25^\circ + x = 180^\circ\).

Step2: Solve for \(x\)

Subtract \(25^\circ\) from both sides: \(x = 180^\circ - 25^\circ\).
Calculate: \(x = 155^\circ\).

Answer:

\(155\)
