Answer:
EY = 60
DW = 68
DE = 128
Step-by-step explanation:
Given
As YW is the perpendicular bisector of EF, then EY = FY
FY = √(FW² - YW²) = √(68² - 32²) = 60
⇒ EY = 60
As WX is the perpendicular bisector of DF, then DW = FW
As FW = 68, then DW = 68
As WZ is the perpendicular bisector of DE, then DZ = EZ = 64
Therefore, DE = DZ + EZ = 64 + 64 = 128
Step-by-step explanation:
For SAS, you need two sides to be in proportion and the included angles to be congruent.
A) included angle between XY and YZ is Y, so wrong
B) included angle between UV and WV is V, so correct.
C) this ratio is just wrong.
D) included angle between XZ and ZY is Z, and the ratios check out, so correct.
