Question

find the value of x.

Explanation:

Step1: Recall sum of interior angles

The sum of interior - angles of a quadrilateral is $(4 - 2)\times180^{\circ}=360^{\circ}$.

Step2: Set up an equation

We have $x + 108+50 + 134=360$.

Step3: Simplify the left - hand side

$x+(108 + 50+134)=x + 292$.

Step4: Solve for x

$x=360 - 292$.
$x = 68$.

Answer:

$68$
