Question

find the value of x.

Explanation:

Step1: Use the triangle angle sum theorem

The sum of the interior angles of a triangle is \(180^{\circ}\). So, \(x + 37+72=180\).

Step2: Solve for \(x\)

Simplify the left - hand side: \(x+109 = 180\). Then subtract 109 from both sides: \(x=180 - 109\).

Answer:

\(71\)
