This trapezoid is made up of two right triangles and one rectangle. Drag numbers to show the area of each triangle and the area of the rectangle. Then drag a number to show the total area of the trapezoid.
help plz

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct
