Q.12 (i) x = sum of all interior angles other than the angle at point D (as it is reflex angle of x)
thus, x = 45°+35°+50° = 130°
[as sum of all angles of a quad. is 360° then x = 360° - reflex angle x . which gives same conclusion as above]
Q.12 (ii) as AB || CD then angle D = 52° (alt. int. angles)
then by angle sum property of a ∆ we have x= 180°- 40° -52° = 88° .
Q.13 . see attachment
Q.14 . see attachment
Q. 15 . I have doubt regarding this questions' correctness or i am not that able to solve it.
thanks . i tried my best.
