Question

the diagram shows a triangle.
what is the value of b?
b = \square^\circ

Explanation:

Step1: Recall triangle angle sum

The sum of angles in a triangle is \(180^\circ\).

Step2: Set up the equation

Let the angles be \(63^\circ\), \(81^\circ\), and \(b\). So, \(63 + 81 + b = 180\).

Step3: Solve for \(b\)

First, calculate \(63 + 81 = 144\). Then, \(b = 180 - 144 = 36\).

Answer:

\(36\)
