Question

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

Explanation:

Step1: Recall the sum of angles in a triangle

The sum of the interior angles of a triangle is \(180^{\circ}\). So, \(55^{\circ}+68^{\circ}+b = 180^{\circ}\).

Step2: Solve for \(b\)

First, calculate \(55 + 68=123\). Then, \(b=180 - 123\).

Answer:

\(b = 57^{\circ}\)
