In the diagram below ab is parallel to cd what is the value of x ?
a; 80
b; 100
c; 120
d: 60

C

Step-by-step explanation:

Since the lines are parallel then

x and 120 are alternate angles and congruent, hence

x = 120 → C

Option C is correct.

Step-by-step explanation:

We are given that line  and line are parallel to each other.

We have to find value of x.

Measure of given angle = 120°

Clearly from pic,

Given angle and x are interior angles and on the alternate sides.

So using a result of parallel line which says that Alternate interior angles are equal.

So, x = 120°

Therefore, Option C is correct.

b is the answer that makes most sense

step-by-step explanation:

answer: 140

step-by-step explanation:

so just add all then it will be your answer but i am not pretty sur eif it is but hope this i am here to people
