Answer 1

Answer:

The correct option is:  D. 10

Step-by-step explanation:

According to the given diagram, the distance from point $Y$ to $\overleftrightarrow{WX}$ is $YZ$.

In the right triangle $XYZ$, the given lengths are:  $XY=10\sqrt{2},\ \ XZ=10$

Using the Pythagorean theorem, we will get......

$(XZ)^2+(YZ)^2=(XY)^2\\ \\ (10)^2+(YZ)^2=(10\sqrt{2})^2\\ \\ 100+(YZ)^2=200\\ \\ (YZ)^2=200-100\\ \\ (YZ)^2=100\\ \\ YZ=\sqrt{100}=10$

So, the distance from point $Y$ to $\overleftrightarrow{WX}$ is 10.

Answer 2

Answer:

By the pythagoras theorem

(10√2)^2 = ZY^2 + 10^2

ZY =  √(200-100)

= 10 answer
