Question

find the value of x.

Explanation:

Step1: Recall angle - sum property

The sum of interior angles of a triangle is 180°. So, \(x + 101+49=180\).

Step2: Simplify the left - hand side

\(x+(101 + 49)=x + 150\). So, \(x+150 = 180\).

Step3: Solve for x

Subtract 150 from both sides: \(x=180 - 150\).
