I cant see the picture good can you write it out not in picture because it is blury for me I dont know about the others
The slope is m=3/4. Hope this helped you with your work let me know if I got the answer correct.
130 revolutions is 130×85π=34714.60cm=347.146m or 347m to the nearest metre.
A^2 + b^2 = c^2
3^2 + 4^2 = c^2
9 + 16 = c^2
25 = c^2
5 = c
You solve by with by altitude! Hope it helps
