Question

If m∠B = 37°, and m∠D = 55°, what is arc DC???....someone please help me

Answer 1

do you have a pic for this?

Answer 2

if m∠B = 37°, then what is arc AD

Answer 3

I'm not sure :/

Answer 4

actually I found a faster way to do this

Answer 5

since BD is a straight line that goes through the center, we know that arc DAB is 180 degrees

Answer 6

if angle D = 55 degrees, we know that arc BC = 2*55 = 110 degrees

Answer 7

so if we know this much of the circle



we can easily subtract that from 360 to get our answer
