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.
Ah, one of my FAVORITES!
1. Take 2 points, ill take (0, 0) and (4, 12)
2. Set them as "1" and "2" so (0, 0) be 1 and (4, 12) be 2.
3.
and insert the equations.
4. You get
which simplifies to 
.
5.
=3
6. Slope = 3
Hope this helps ^^

Answer:
x = 5.477 s
Step-by-step explanation:
Your full question can be found in the image below
We can easily solve this question by using a graphing tool or calculator to plot the equation
f(x)=-5x^2 +200
See second attached picture
The ball is 50 meters from the ground when
50 =-5x^2 +200
-150 =-5x^2
x^2 = 30
x = 5.477 s
