Question

solve the problem given below

Answer 1

draw a dotted line parallel to AB and CD through x
then,OD and OB will be the transversals that connect AB and CD
name a point p that is on the dotted line
angle cdo+angle dop=180°
it is angles on the same side of the transversal
angle dop = 180°-35°
angle dop=145°
angle abo +angle bop=180°
angle bop =180°-40°
angle bop=140°
angle bop+angle dop=x
140°+145°
=285°
the value of angle x is 285°
x is the reflex of angle BOD
