Answer:
x = √(w(w+z))
Step-by-step explanation:
The idea with a right-triangle figure of this sort is that all of the triangles are similar. Here, x is the short side of ∆ABC, and the hypotenuse of ∆BDC. This suggests you want to write a similarity statement involving the short side and hypotenuse.
BC/AC = DC/BC . . . . . short side/hypotenuse
BC² = AC·DC . . . . . . cross multiply
x² = (w+z)w . . . . . . substitute letter values
Taking the square root and rearranging to the form of the applicable answer choice, this is ...

The computation shows that the total amount or cost raised will be $250.
<h3>How to calculate the cost?</h3>
From the information given, it was stated that the skating club collected $8 from each of the nine members and had already raised $178.
Therefore, the total amount will be;
= $178 + ($8 × 9)
= $178 + $72
= $250
Therefore, the total amount raised will be $250.
