70

Given, x = 20 and y = 30

In the given Quadrilateral, x, x, y are the measures of the three angles and let

′

t

′

be the fourth unknown angle.

Sum of the interior angles of the quadrilateral = 360

⇒x + x + y + t = 360

⇒20 + 20 + 30 + t = 360

⇒t + 70 = 360

⇒t = 360 − 70

⇒t = 290

To find

′

z

′

,

Sum of angles in one turn = 360

Here, t + z = 360
