Question

the measures of the angles of a triangle are shown in the figure below. solve for x.
answer attempt 1 out of 2
x =

Explanation:

Step1: Recall triangle angle sum

The sum of angles in a triangle is $180^\circ$.

Step2: Set up the equation

$90^\circ + 38^\circ + x^\circ = 180^\circ$

Step3: Calculate known angle sum

$90 + 38 = 128$

Step4: Solve for $x$

$x = 180 - 128$

Answer:

$52$
