Question

find x........................!

Answer 1

Sun of all angles of quad = 360

sum of all angles =45+35+50+D=360

360-130=230

angle adc+ angle adc of quad = 360

360=230+x
x=360-230
x=130

Answer 2

The figure above is a quadrilateral.

So,the sum of all of its four sides will be 360°

45+50+35+y=360
130+y=360
360-130=y
230=y(inner angle)

Reflex angle =360°

So x=360-230
130°

X=130°
