    Well you can use the Pythagorean Thereom to get side WX, which rounded off is 14.4, and the triangles look proportional to me, but to check: \[\frac{ WZ }{ WX } = \frac{ WX }{ WY}\] \[\frac{ 10 }{ 14.4 } = \frac{ 14.4 }{ WY }\] Then you cross multiply to get WY= 20.74 WY=WZ+YZ Substitute in values: 20.74= 10+YZ Subtract 10 from both sides: YZ= 10.74

    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
