Answer:
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
⇒z + 290 = 360
⇒z = 360 − 290
⇒z = 70
Therefore, the value of
′
z
′
is
′
70
′
.
