It is 45 yd from the base of the pole.
The pieces of the right triangle we are given are one of the legs (the height of the pole, 60 yd) and the hypotenuse (the length of the cable, 75 yd). Using the Pythagorean theorem, we have:
60²+b²=75²
3600+b²=5625
Subtract 3600 from both sides:
3600+b²-3600=5625-3600
b²=2025
Take the square root of both sides:
√(b²) = √2025
b = 45
It's a flat horizontal line so the slope is 0
Slope = rise/run = 0/run = 0
The "run" can be any number you want as long as it's not 0.
If you want the ratio in its simplest form, then it’s already in its simplest form.
