Question

Help..?
If marc BC = 45°, what is the measure of the corresponding major arc?
I got 315? I'm I right?

Answer 1

Am I*

Answer 2

AB? Yeah it looks like that one is!

Answer 3

The major measures more than 180 degrees

Answer 4

i was going to say, either you are right if the major is the whole remaining angle, or it is 180-45.

Answer 5

what not 360 -45

if you take a 45 degree arc out of the circumference, whats left..?

Answer 6

yes go with your first answer, major is more than 1/2 of a circle

Answer 7

Would the answer then be 135?

Answer 8

I got 315? I'm I right?

Answer 9
