Question

what is the value of y? y = □°

Explanation:

Step1: Use the triangle angle - sum property

The sum of the interior angles of a triangle is \(180^{\circ}\). For \(\triangle CDE\), we have the formula \(y + 48^{\circ}+66^{\circ}=180^{\circ}\).

Step2: Solve for \(y\)

Subtract \(48^{\circ}\) and \(66^{\circ}\) from \(180^{\circ}\).
