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.
Answer:
they need to sell 15,000 because 42 percent of 15,00 is 6,300+2500=800

and the number line should have a closed point on 15,000 with the line pointing to the right
Answer:
the shape is semetrical
Step-by-step explanation:
When we say cubic root, it means that the exponent of your divisor is three. You can solve this by counting how many three's are there in a ten. So there are three three's. the other x has an exponent one and therefore is denoted by ∛x. The answer would be x³∛x.
Answer:
Step-by-step explanation:
let the number be x
(x+6)/3 =21
x+6=21*3
x+6=63
