Question

what is the value of y? y = °

Explanation:

Step1: Recall angle - sum property of a triangle

The sum of the interior angles of a triangle is 180°. In triangle PQR, we know two angles and need to find the third.
Let the angles of the triangle be \(y\), 73°, and 34°. Then \(y + 73^{\circ}+34^{\circ}=180^{\circ}\).

Step2: Solve for \(y\)

We can rewrite the equation as \(y=180^{\circ}-(73^{\circ} + 34^{\circ})\). First, calculate \(73^{\circ}+34^{\circ}=107^{\circ}\). Then \(y = 180^{\circ}-107^{\circ}\).
\(y = 73^{\circ}\)

Answer:

73
