This triangle is an isosceles triangle because the legs are equal. That means the base angles are congruent.
This means that the other angle is also equal to y.
That top angle is equal to 108 since the pentagon is a 'regular' shape.
We know that triangles equal up to 180.
Now we can make our equation.
2y + 108 = 180
Subtract 108 from both sides.
2y = 72
Now divide by 2
y = 36 This is the value of y.
