Answer 1

hey mate !!❤✌
here's ur answer ✍✍✍

Given :- AB//CD
angle B = 135°
angle D ℅ 145°

To find :- x

Construction :- Draw a line EF//AB//CD in such a way that it bisects angle O

Solution :- Let angle BOF be angle 1
and angle FOD be angle 2

Now angle B + angle 1 = 180° ( angles on the same side if transversal )
because AB //EF so BO is a transversal

135+angle 1 = 180
so angle 1 = 180-135
angle 1 = 45°

//ly angle 2+angle D = 180
angle 2 = 180-145
angle 2 = 35°

ANGLE X = ANGLE 1 + ANGLE 2
X = 45+35
$\huge\boxed{ x = 80}$
