Question

find the value of x.

Explanation:

Step1: Recall triangle angle sum

The sum of angles in a triangle is \(180^\circ\). So, \(x + 78 + 53 = 180\).

Step2: Simplify and solve for \(x\)

First, add \(78\) and \(53\): \(78 + 53 = 131\). Then, \(x + 131 = 180\). Subtract \(131\) from both sides: \(x = 180 - 131 = 49\).

Answer:

\(49\)
