Answer:
s is 22
Step-by-step explanation:
Notice that we are dealing with two similar triangles (UTW and XVW) which have the characteristic that the sides of the larger one are twice the size of the smaller triangle's sides. TW = 2 XW, UW = 2 VW, and therefore TU = 2 VX
then we use the expressions they gave us for TU and for VX in the equation above:
TU = 2 VX
s + 22 = 2 * s
subtract s from both sides:
22 = 2 s - s
22 = s
Therefore, s is 22.
