Question

what is the value of h?

Explanation:

Step1: Use vertical angles property

Vertical angles are equal. Let's assume the sum of \(h + 30.3^{\circ}\) and \(72.5^{\circ}\) are vertical angles. Since vertical angles are equal and the sum of angles on a straight - line is \(180^{\circ}\), we know that \(h+30.3^{\circ}+72.5^{\circ}=180^{\circ}\) (because they form a linear pair with the vertical angle of \(h + 30.3^{\circ}+72.5^{\circ}\)).

Step2: Solve for \(h\)
