Question

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

Explanation:

Step1: Recall triangle angle sum

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

Step2: Calculate \(t\)

We know two angles: \(36^\circ\) and \(66^\circ\). So, \(t = 180^\circ - 36^\circ - 66^\circ\).
First, \(36 + 66 = 102\). Then, \(180 - 102 = 78\).

Answer:

\(t = 78^\circ\)
