Answer 11

@sdfghj How would that help me find angle ced

Answer 12

try filling out angles you can find.

Answer 13

But i have to used inscribed angles right?

Answer 14

I dont understand this is so stupid

Answer 15

i don't think so. there has to be some formula @amistre64

Answer 16

i figured out the formula. I think you add 48+32 and divide by 2 because its an inscribed angle

Answer 17

82 not 32

Answer 18

Well that comes to 65 which is one of the options

Answer 23

your post is missing information ..... but i think i can see past it



the central angles define the arcs, and the angle of crossing is simply an average of the subtended arcs.
