We know that in a triangle WXY,

And we want to find the value of x and the length of each side. For doing so, we will do a figure:
And, as the angles X and Y are congruent, the opposite sides to those two angles are also congruent (the sides shown):
Thus:

Which means that:

This means that the value of x is 4. Now, we replace the value of x on each expression to find the measure of the sides:

This means that WX=WY=25 and XY=17.
