If m 12 years ago

Answer 1

By the way, I already know that the answer is 70, but how did they come up with that?

Answer 2

Angle ABD is a flat angle, meaning it measures 180

So that means: (angle BDC) + (angle ABC) = 180

Answer 3

110 + (angle ABC) = 180
angle ABC = 180 - 110

Answer 4

OMGoshh Thank You!!! That makes so much sense now. I will now grant you your medal! -Blu

Answer 6

If m<DBC =110 degrees and AB = 4, m arc AC = ?

Answer 7

Never mind, I figured it out, and realized that the Arc was actually the same as the angle ABC, just the Arc itself is 70, so either way I'd get the same thing, that's so neat. Hopefully you understand what I'm saying.
