Question

In the given figure, find x
​

Answer 1

Answer:

x = 285 , as dotted line is also parallel to other lines.

Divide x into x1 and x2 ( as divided by the dotted line )

x1 + x2 = x

x1 + 30° = 180° ( sum of internal angles in a ||gm is 180° )

x1 = 150°.

x2 + 45° = 180° ( sum of internal angles in a ||gm is 180° )

x2 = 135°.

x = x1 + x2 = 150° + 135° = 285 °
