Answer:
80
Step-by-step explanation:
This quadrilateral is a kite
And the kite as its opposite angles equal
So based on this we can solve for x
[tex]100 + 100 + x + x = 360[/tex]
(360 here is the total sum of interior angke in a quadrilateral)
[tex]200 + 2x = 360 \\ 2x = 360 - 200 \\ 2x = 160 \\ x = \frac{160}{2} \\ x = 80[/tex]
Thisbis your answer hope it helps :))
