Answer:
50
Step-by-step explanation:
This is an isosceles triangle which means opposite sides are congruent implies the base opposite angles at the base congruent.
So both of bottom angles are 65 each.
We know the sum of the interior angles of a triangle are 180 degrees.
So we have 65+65+x=180.
Combine like terms:
130+x=180
Subtract 130 on both sides:
x=180-130
x=50
