Question

how many degrees is angle x?

Explanation:

Step1: Use the straight - angle property

A straight angle is \(180^{\circ}\). If one of the adjacent angles is \(130^{\circ}\), and let the other angle be \(x\).
We know that \(x + 130^{\circ}=180^{\circ}\) (because they form a straight - line pair of angles).

Step2: Solve for \(x\)

Subtract \(130^{\circ}\) from both sides of the equation \(x + 130^{\circ}=180^{\circ}\).
\(x=180^{\circ}-130^{\circ}\)
\(x = 50^{\circ}\)

Answer:

\(50^{\circ}\)
