Question

How to solve for a b and c ​

Answer 1

So B is 140 because D is 140, A and C are 40 because 140+140=280. 360-280=80 Divided by 2 equals 40

Answer 2

a=40. b=140. c= 40

Explanation:

b is congruent To 140 because of the vertical angles postulate that states two angles vertical from one another are congruent.

a is 40 because it is Supplementary to b Which means that the sum of a and b must add up to 180.

c is Congruent to a due to the vertical angles postulate
