Answer:
x = 50
Explanation:
Since the 2 sides are equal to each other, so are the angles. This is an isoceles triangle, by the way. All triangle interior angles add up to 180.
So, the equation is:
x + 65 + 65 = 180
x + 130 = 180
x = 180 - 130
the two angles at the bottom would he the same. Since the interior angles of a triangle must add up to 180 the you just subtract that from 180. 180-(65+65)=50
