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.

When you know the coordinates of a point and the slope of a line, you can use the formula

in your case,  and
 and  , so you have
, so you have

Step-by-step explanation:
LET THE Point 1 A and point 2 is B
(AB) ^2=(-9-(-3))^2+ (5-(-6))^2+(-4-7)^2=278
AB=16.67 length unit
Midpoint 
X=-9-3/2 =-6
Y=5-6/2=-0.5
Z=-4+7/2=-1.5
