Question

CAN SOMEONE PLEASEEE EXPLAIN ME TO HOW TO DO THIS!!!! I AM SOOO CONFUSED.

Answer 1

It's a trick question. You're suppesed to use process of elimination

Answer 2

Pythagorean theorem

Answer 3

is 12 the length of the full chord or half?

Answer 4

@ zarkon oh right, duh...

Answer 5

make a right triangle with 16 and 12, and x being the hypotenuse. Use the pythagorean theorum to find the length of x

Answer 6

12 must be half of the cord

Answer 7

if you draw a line between the center and the intersection of the chord, you get a nice little triangle with the radius as the hyp, and then, it's all gravy from there

Answer 8

a=12/2=6
b=16
a^2+b^2=c^2

substitute & solve

Answer 9

I think you want to use a=12

Answer 10

then you get a Pythagorean triple

Answer 11

Thank you guys!!! That helped!!!
