Below is an isosceles trapezoid.

To answer the exercise, certain information is needed:
In a quadrilateral the sum of the interior angles is 180.
The isosceles trapezoid has equal angles.
From here it is we know that the sum of the angles adjacent to a side of the trapezoid is 180°.
We turn this conclusion into an exercise:
2y+20+60=180
We add up the relevant angles
2y+80=180
We move the sections:
2y=180-80
2y=100
Divided by 2
y=50
When we substitute Y we get:
2(50)+20=120
And this is the solution!
120°
True OR False:
In all isosceles trapezoids the base Angles are equal.
