Respuesta :

The sum of interior angles of a trapezoid is 360°.

The pair of bottom angles are equal, also the pair of top angles.

So:

(4x) + 4x + (6x+20) + (6x+20) = 360

Solve for x:

4x + 4x +6x +20 +6x + 20 = 360

Combine like terms:

4x+4x+6x+6x +20+20 =360

20 x + 40 = 360

20x = 360-40

20x = 320

x = 320/20

x = 16

Replace x on (6x+20)

6(16)+20 = 116°

y= 116°
