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.)
I JUST POSTED IT STEWP3D.
What are your answer choices? o:
They give me none. ):
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
Good luck in all of your studies and thx for the recognition! you're welcome! @marcoduuuh
