Question

what is the value of y? 60° 25° y

Explanation:

Step1: Recall angle - sum property

The sum of angles around a point is 360°. But we can also use the fact that vertical angles are equal and the sum of angles on a straight - line is 180°. Here, we note that the three angles 60°, 25°, and y are on a straight - line.

Step2: Set up the equation

Since the sum of angles on a straight - line is 180°, we have the equation \(60^{\circ}+25^{\circ}+y = 180^{\circ}\).

Step3: Solve for y

First, add 60° and 25°: \(60 + 25=85\). Then, rewrite the equation as \(85^{\circ}+y = 180^{\circ}\). Subtract 85° from both sides: \(y=180^{\circ}-85^{\circ}\).
