Question: WV is the diameter and equals 16. XY is perpendicular to it, and equals 10. They intersect at pt. Z. I need to know what WZ equals. Please help! Hi Ashlie,
In the diagram below I let x be the length of WZ and then the length of ZV is 16  x. XZ^{ 2} + ZV^{ 2} = VX^{ 2} and VX^{ 2} + XW^{ 2} = WV^{ 2} 5^{ 2} + (16  x)^{ 2} = VX^{ 2} and VX^{ 2} + XW^{ 2} = 16^{ 2}
