Answer 11

Here you need some information form geometry about triangles.
Notice the two small marks on sides JK and JL.
Those marks mean the sides are congruent (they have the same length).
In a triangle, if two sides are congruent, then their opposite angles are congruent.
That means angles K and L are congruent.
That means that when you write the equation for the angle measures, a + b + c = 180,
you write x + x + 10 = 180
Now solve for x.
