Question

mR = 50°. Find mO. The figure is not drawn to scale.

Answer 1

kind of the same rule as before

Answer 2

the angle from the base of the circle to the arc is half

Answer 3

and if nq is 100 then thats the same as the one in center

Answer 4

dont take my word about that base angle being half of the arc though im just using a theorm but u shud see the proof for it.. thats the fun part with geometry

Answer 5

Ohh, so they are equal?

Answer 6

yes, well if NQ is 100 degrees then u know thats the same as center one

Answer 7

Oh okay, well thank you!

Answer 8
