In AVWX, the measure of ZX=90°, VX = 48, WV = 73, and XW = 55. What is the value of the tangent of ZW to the nearest hundredth?

For 3. It is the fourth choice. This is because angle DGF is vertical angle and thus equal to angle EGB. Then angle BGF is supplementary to this angle.
So your answer is EGB+BGF=180

For 4. It is the first choice of 62 ft. It is the midpoint so is half the total line segment.
