Question

the diagram shows a triangle.
what is the value of x?
x = \square^\circ

Explanation:

Step1: Sum triangle angles to 180°

$33 + 93 + 18x = 180$

Step2: Simplify left side

$126 + 18x = 180$

Step3: Isolate the term with x

$18x = 180 - 126$
$18x = 54$

Step4: Solve for x

$x = \frac{54}{18}$

Answer:

$3$
