Triangle WXY has side lengths XY=14 and WX=8 . The tangent to the circumcircle of triangle WXY at X is drawn, and the line through W that is parallel to this tangent intersects XY at Z. Find YZ.

 

 

 

Thank you so much!!!

By similar triangles, YZ = 23/4.

This question was answered here 

Its always a good idea to search your problem before you post it. 

A lot of problems have already been answered so there is no point in posting it here.

Here's the answer:

 

Let a triangle WXY be a right-angled triangle.

 

 XY = 14            WX = 8

 

tan(Y) = 8 / 14        ∠Y  =  ∠XWZ  = 29.7448813°

 

XZ = tan(XWZ) * WX = 4.571428571

 

YZ = XY - XZ = 9.428571429  laugh

 

( This is the correct answer!!! Believe me.cool)

How do you know that both of those answers are incorrect? What's the correct answer, then???

Is this rounded? If so, could you please give the exact answer?---------> for post 5

I don't know, that is why I still haven't said I got the answer.

This only works in a right triangle.

It would help if there were not two threads running for this question.

There is another thread which does contain the correct solution and the correct answer, 66/7.

#5 above should be disregarded, it considers only the specific case where WY is a diameter of the circle.

WY is parallel to the tangent a X, it needn't be the diameter.
