I Give Brainiest In the figure above, AD intersects BE at C. If x=100 , what is the value of y?

A) 100

B) 60

C) 90

D) 80

The answer is D), 80.

Step-by-step explanation:

All sides of a triangle must add up to 180°. So, if x = 100, angle BCA must equal 60° because 180 - 120 = 60. Since angles BCA and DCE are vertical angles, they are equal, making angles DCE 60°. All you need to do now is add up 60 + 40; that should give you 100. You also need to subtract that from 180 to get your final answer of y = 80°.
