Question

12. In the given figure, AB CD. Find the value of x.​

Answer 1

Answer:

because lines AB and CD are parallel, angle CAB is equal to angle FCD.

Therefore the angle FCE is equal to angle DCE (straight line) - angle FCE =

180 - 75 = 105

Because all internal angles in a triangle add up to 180:

180 = 75 + 30 + x

180 = 105 + x

x = 180 - 105

x = 75
