The hill means it was already 23 feet above ground and he went and back up so the answer is 23 positive

Euclid
h^2=4.6
h=2 square root of 6
h^2+6^2=base^2
24+36=base^2
base=2square root of 15
h^2+4^2=height^2
24+16=height^2
height=2 square root of 10
F = 41
E = 90
D = 49
from D to E is 55
then E to F also known as X = 36.08 or 41.51
The answer should be 6.34. This is because since the 6 is in the ones place, it should be the whole number. The 3 is a tenths so it should be the first number after the decimal. Finally, since 4 is in the hundredths place, it should be two places from the whole number.
