21 because you turn the 5 yards in to feet which is 15, then you add 15+4+2=21
15.25m/1gallon=Xm/12.5gallons so the SUV will travel 190.625m
The car will travel 330m
330-190.625=139.375 more miles
For every possible angle
, the fundamental law of trigonometric states that

In your case, the inputs you provided would lead to

So, it is not possible that, for a certain angle x, we have
