Question

find the measure of the missing angles.
answer
attempt 1 out of 2
b =
c =

Explanation:

Step1: Find the value of \(b\)

Vertical angles are equal. The angle of \(31^{\circ}\) and \(b\) are vertical angles. So \(b = 31^{\circ}\)

Step2: Find the value of \(c\)

\(c\) and \(31^{\circ}\) are supplementary angles (they form a linear - pair). The sum of supplementary angles is \(180^{\circ}\). So \(c=180 - 31\)
\(c = 149^{\circ}\)

Answer:

\(b = 31^{\circ}\), \(c = 149^{\circ}\)
