Answer:
82 Degrees
Explanation:
This is an isosceles triangle as I’m sure you know. This means that the 2 sides with marks are identical as well as the vertex below each side.
The angle labled 131 degrees and the angle next to it add to 180 degrees.
You take 180-131 to get 49 Degrees. The angle to the left of it is identical.
So the bottom 2 angles add up to 98 degrees.
All triangle interior angles add up to 180.
Take 180-98 to find x.
Your answer is 82 degrees
