Question

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

Explanation:

Step1: Recall triangle angle sum

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

Step2: Calculate the third angle

Let the angles be \(95^\circ\), \(42^\circ\), and \(y\). So, \(y = 180 - 95 - 42\).
First, \(95 + 42 = 137\). Then, \(180 - 137 = 43\).

Answer:

\(y = 43^\circ\)
