Here we have three similar triangles
In similar triangles sides are in proportion
The altitude to the hypotenuse of a right triangle is the mean proportional between the segments into which it divides the hypotenuse.
![\frac{part of hypotenuse }{altitude} =\frac{altitude}{other part of hypotenuse}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bpart%20of%20hypotenuse%20%7D%7Baltitude%7D%20%3D%5Cfrac%7Baltitude%7D%7Bother%20part%20of%20hypotenuse%7D%20%20)
![\frac{16}{y} =\frac{y}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B16%7D%7By%7D%20%3D%5Cfrac%7By%7D%7B4%7D%20%20)
We cross multiply to solve for y
![y^{2} =64](https://tex.z-dn.net/?f=%20y%5E%7B2%7D%20%3D64%20)
Taking root of both sides
y=8
This is true.
If the end point of the line FG line in the same plane, then all of the points on the line FG will lie on the same plane. But this is only true if the FG line is a straight line.
If FG is a curved line this statement can but does not have to be true.
B because 7 and 9 can go into it since they are factors of 63. The rest of the numbers don’t have any prime number except for one and itself
Answer: hey u ever find out? i would love to know
