Answer:
Part 1) 
Part 2) The measure of the interior angles are 64°-67°-49°
Step-by-step explanation:
see the attached figure to better understand the problem
step 1
Find the value of x
we know that
The sum of the interior angles in any triangle must be equal to 180 degrees
so
In this problem

Solve for x
Combine like terms

Subtract 18 both sides


Divide by 6 both sides

step 2
Find the measure of each interior angle
substitute the value of x in each measure
