Question

In the given figure, AB || CD. If AOC = 30°
and OAB = 100° then OCD = ?​

Answer 1

Answer:

Correct option is

A

130o





Answer 2

Answer:

130

Step-by-step explanation:

First construct a line parallel to AB from OP

Now,

AB and OP parallel and AO transverse

So, angle AOP=180-100=80

Therefore

Angle COP=80-30=50

Now,

CD parallel to OP

And transverse CO

So, angle OCD=180-50=130
