You didn't say whether you needed this expressed in a mathematical formula, but knowing the answer already, it shouldn't be hard to come up with one if necessary.
Hope this helps.
Answer:
x = 71
Step-by-step explanation:
Since 2 sides of the triangle are congruent then the triangle is isosceles.
Thus the 2 base angles are congruent
The sum of the 3 angles in the triangle = 180°, so
x = 
= 
= 71
