Question

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

Explanation:

Step1: Recall triangle angle sum

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

Step2: Calculate \(v\)

Let the angles be \(42^\circ\), \(84^\circ\), and \(v\). So, \(v = 180 - 42 - 84\).
Calculate \(180 - 42 = 138\), then \(138 - 84 = 54\).

Answer:

\(v = 54^\circ\)
