Question

In the diagram below, is an altitude of WXY. What is the length of ? If necessary, round your answer to two decimal places.

(Picture below.)

Answer 1

Below is the solution for the given problem above:

WX = 10 sqrt(2) by the Pythagorean Theorem.

WY/WX = WX/10 because of similar triangles.
 
WY = [(WX)^2]/10 = 20
 
WY = WZ + YZ
 
YZ = 10

I hope this helps!
