Question

find the measure of the missing angle.
answer attempt 1 out of 2
a =

Explanation:

Step1: Use the property of adjacent angles on a straight line

Adjacent angles on a straight line sum to \(180^{\circ}\). So, \(a + 130^{\circ}=180^{\circ}\).

Step2: Solve for \(a\)

Subtract \(130^{\circ}\) from both sides of the equation: \(a=180^{\circ}- 130^{\circ}\).

Answer:

\(50\)
