+128475 A) You can use the same diagram.....just add segment HE
This segment will form one leg of right triangle HEJ = 3960 miles
And JE forms the hypotenuse = GE + JG = 3960 + 6 = 3966 miles
B) So....using the Pythagorean Theorem
JH =
sqrt ( JE^2 - HE^2 ) =
sqrt (3966^2 - 3960^2 ) =
sqrt (47556) ≈
C) 218.1 miles = distance to the horizon
