Question

what is the value of b?

Explanation:

Step1: Identify angle - relationship

The larger angle of 71° is composed of the angle \(b\) and the 43° angle.

Step2: Set up subtraction formula

We can find \(b\) by subtracting 43° from 71°, so \(b = 71^{\circ}-43^{\circ}\).

Step3: Calculate the value of \(b\)

\(b=28^{\circ}\)

Answer:

\(28\)
