Question

If m∠B = 52 and m∠ECD = 63, what is the measure of ∠ACB?

Answer 1

diagram?

Answer 2

Were you told about any lines being parallel?

Answer 3

No, it only showed the diagram and question./:

Answer 4

One second, I will help

Answer 5

Okay, thanks!

Answer 6

Alright, here we go. Because of the rules of triangles, angle "ABC" = angle "BCD". Given those two angles, and knowing that straight lines always have a degree measurement of 180, you should be able to find angle "ACB"

What rule says that angle ABC = angle BCD? Please name such a rule or theorem. I would be delighted to hear about it.

Answer 8

To be honest I'm completely lost i just know that a triangle equals 180 degrees lol

Answer 9

@marilynmanson_98

I never heard of such a rule and I do not think that enough information is given to solve the problem.
