Question

if m and n are parallel and angle 1 is 135°, what is the measure of angle 2? (1 point)

Explanation:

Step1: Use the property of adjacent angles

Adjacent angles on a straight line sum to \(180^{\circ}\). So, \(\angle1+\angle2 = 180^{\circ}\)

Step2: Solve for \(\angle2\)

Given \(\angle1 = 135^{\circ}\), then \(\angle2=180^{\circ}-\angle1\)
Substitute \(\angle1 = 135^{\circ}\) into the formula: \(\angle2 = 180^{\circ}- 135^{\circ}\)

Answer:

\(45^{\circ}\)
