Question

the measure of an angle is 1°. what is the measure of its supplementary angle?

submit

Explanation:

Step1: Recall supplementary angle definition

Supplementary angles sum to \(180^\circ\). Let the angle be \(x = 1^\circ\), and its supplement be \(y\). Then \(x + y = 180^\circ\).

Step2: Solve for the supplement

Substitute \(x = 1^\circ\) into the equation: \(1^\circ + y = 180^\circ\). Subtract \(1^\circ\) from both sides: \(y = 180^\circ - 1^\circ = 179^\circ\).

Answer:

\(179^\circ\)
