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
_____
<em>Additional comment</em>
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.

stay safe healthy and happy.
Step-by-step explanation:
Put the value y.
-2x-8(-5x+22)=14
-2x+40x-176= 14
38x-176 =14
38x = 190
x=5
Now put the value of X to find Y
Y= -5(5)+22= -25+22 = -3
=>X=. 5
=>Y= -3
Answer:
Step-by-step explanation:
Tan 34 = 
Where opposite = 29, adjacent = AC
So,
0.674 = 
AC = 
AC = 42.99
Answer:
It is, indeed, a reduction. But, the scale factor of the dilation should be a fraction instead of a whole number, since the shape has shrunk.
Instead of 
, it should be 
. That would make it (4 - 2) / (8 - 4) = 2 / 4 = 1/2.
Hope this helps!
