Subtract these 2 equations,
5x-5x +3y-y = -4-6
2y = -10
y = -5
-5 is your answer.
We are given
height = 3.7 mi
radius = 3959 mi
We are asked for the distance between the man and the horizon
The straight line from the man to the horizon is a tangent line to the surface of the earth
Using Pythagorean theorem
(3.7 + 3959)² = 3959² + d²
Solve for d
d = 171 mi
0-0.59 because the number has to be less than 0.6 and all numbers up to 0.59 are not greater than 0.6
You can’t really know the y value unless you’re told that they’re both directly proportional. if so, then check out the pic
