Answer 2

Step-by-step explanation:

Let the quadrilateral be ABCD

as we can see <A = 90°

<B = 180 - 100 ( exterior angle property)

= 80°

<D = 180 - 70 ( exterior angle property)

= 110°

x = <A + <B + x + <D = 360°

x = 90° + 80° + 110° + x = 360°

280° + x = 360°

x = 360° - 280°

x = 80° ans
