Answer 1

is it simply 12-10?

Answer 2

careful. XZ is not tangent here to simply do that

Answer 3

First up, I have to mark up the diagram.

Why do you think the answer is 2? @stupidinmath

Answer 4

guessing :|

Answer 5

@stupidinmath On the diagram, do you agree that OW is a radius of the circle?

And, do you see that XY is a diameter of the same circle?

So, OW =

Answer 6

ZY/2 = OW?
OW=5

Answer 7

Look at the diagram now.

Answer 8

So.. 12 - 5
so YZ= 7?

Answer 9

stop guessing ;p

Answer 10

WOZ is a right triangle with legs of lengths 5 and 12.

Part of the hypotenuse is 5 but we need the other part.

So, you can use the Pythagorean Theorem to find hypotenuse OZ and then subtract 5 from that to get YZ.

If you remember the Pythagorean Triple (5, 12, 13) the solution will be a little faster but not too much faster. :)

Answer 11

@ganeshie8 haha alright..

Answer 12

5² + 12² = (OZ)² --> solve for OZ @stupidinmath

Answer 13

13

Answer 14

OZ = 13.
