Question 1062091
v for iVan's distance;
b for Bucky's distance;
from the tree bottom.
y for how high the tree from bottom to top.


Draw your picture.
Two Right Triangles, sharing the side y.


{{{system(v+b=65,tan(30)=y/v,tan(35)=y/b)}}}


Can you find what to do with that system and solve for the value of y?
