Answer:
YZ=80 so UZ = 1/2 YZ= 40
SZ=120 so SU = square root of 120 square (SZ)+ 40 square (UZ) = 80x square roof of 2.
SY = square root of 40 square (YU) + square SU = 120
VS=72 given
YV = square root of 120 square + 27 square = 96
If you know VS and VX, you should know how to calculate XS. XS=120.
