Answer 1

I don't know answer to this question

Answer 2

we know that sum of angles of a quadrilateral is 360°so angleA +angle B+angle C +reflex of angle D =360° (reflex of an angle is 360° minus the given angle)
35°+45°+50°+reflex of angle D =360°
130°+reflex of angle D = 360 °
reflex of angle D =360°-130°
reflex of angle D =230°
HENCE x=360°-230°x=130°
