Question

IF AB is parallel to CD find x

Answer 1

Step-by-step explanation:

x + Angle B + Angle C =360

x+110+100=360

x+210=360

x=360-210

x=150

Answer 2

Let let the angleA be x

now

according to question

A + Angle B + angle C = 360

X + 110 + 100 = 360

X + 210 = 360

X = 360 - 210

X = 150

let the angle A = 150
