Question

what is the value of Q?
8.25
16.5
8.8
4.4

Answer 1

is there some theorem saying that a chord that is perpendicular to a radius is bisected?

Answer 2

so the entire chord is 8.25*2 = 16.5

Answer 3

and the other one is the same distance from the center and perpendicular, so it would be the same length

Answer 4

you can prove using triangle congruence

Answer 5

Because the distance of the 2 lines from the center point are the same distance (4.4), AND they have right angles, both chords are the same length.

just multiply 8.25 by 2 for chord q

Answer 6

right. ic that
