Question

find the value of y.
56°
y
72°

Explanation:

Step1: Recall the sum of angles in a triangle

The sum of the interior angles of a triangle is \(180^{\circ}\).

Step2: Set up the equation

Let the three angles of the triangle be \(56^{\circ}\), \(72^{\circ}\), and \(y\). Then \(56 + 72+y=180\).

Step3: Solve for \(y\)

First, calculate \(56 + 72 = 128\). Then \(y=180 - 128\).
\(y = 52\)

Answer:

\(52\)
