Question

follow the steps to find the area of the shaded region. the height (h) is needed to find the area of the triangle. some imaginary lines have been drawn to help find it. start by find the measure of angle x. angle x = ?°

Explanation:

Step1: Use the property of adjacent angles

Adjacent angles on a straight line sum to \(180^{\circ}\).
So, \(x + 129^{\circ}=180^{\circ}\)

Step2: Solve for \(x\)

Subtract \(129^{\circ}\) from both sides of the equation.
\(x=180^{\circ}- 129^{\circ}\)

Answer:

\(51\)
