Question

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

Explanation:

Step1: Recall triangle angle sum

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

Step2: Calculate \(z\)

Given angles are \(40^\circ\) and \(42^\circ\). So, \(z = 180 - 40 - 42\).
\(z = 98\).

Answer:

\(98\)
