Question

find the value of x.

Explanation:

Step1: Recall angle - sum property of a triangle

The sum of interior angles of a triangle is 180°. So, \(x + 50+80=180\).

Step2: Solve the equation for \(x\)

First, simplify the left - hand side: \(x + 130 = 180\). Then, subtract 130 from both sides: \(x=180 - 130\).

Answer:

\(x = 50\)
