Step-by-step explanation:
The end of the ladder touches the top of the tree when kept at 2.8m away from the tree.

Answer: r = -5/18
Step-by-step explanation: You solve -3(1+6r)+12=14
-3-18r+12=14 (When distributed)
-18r+9=14
-18r=5
r=-5/18
Area of a Triangle = 1/2(Base times Height)
7500=1/2(200*h)
3750=100*h/2
3750/100=h/2
37.5=h/2
37.5*2=h
h=75yd
hope it helps
