Answer:
86.63 ft
Step-by-step explanation:
The tangent relation applies.
Tan = Opposite/Adjacent
tan(77°) = (tree height)/(20 ft)
tree height = (20 ft)·tan(77°) ≈ 86.63 ft

It is somewhat problematic for Bob to see the top of a white pine tree at that angle of elevation. His view would likely be obscured by the branches of the tree.
The unit price for a can would be 3.00 / 2 = 1.50 per can
so for every can you add, you would also add 1.50 to the price.
the answer would be:
<span>Because the final price is a function of the number of cans</span>
Three times four is twelve so 6+6=12or9+3=12
4x4 = 16
2x2 = 4
16-4 = 12
12 is the area of the part shaded
This will help
The square has a side of 38, so dividing that by 2 will give you the radius of the circle inside of it. The radius would be 19, and using it in the circle area formula(πr^2) will give you the answer:
A=pi(19)^2
A=361pi
A= 1133.54inches^2
