Question

find the value of x.

Explanation:

Step1: Use the property of complementary angles

The sum of two complementary angles is \(90^{\circ}\). So, \(50+(x - 12)=90\).

Step2: Solve the equation

First, simplify the left - hand side of the equation: \(50+x-12=x + 38\). Then the equation becomes \(x + 38=90\). Subtract 38 from both sides: \(x=90 - 38\).

Answer:

\(x = 52\)
