Answer:
h=4
Step-by-step explanation:
a^2 = h^2 + 4
b^2 = h^2 + 64
(2 + 8 )^2 = a^2 + b^2
100 = h^2 + 4 + h^2 + 64
100-68 = 2h^2
32 = h^2
h = 4

18 feet and 4.5 inches
<u>Explanation
</u>
You are going to use the concept of similar triangle.
∆CED≡∆CBA
This is because they share the angle at C and also they both have an angle of 90o.
Let EC = X, then BE = 2.5X. So, BE = (X + 2.5X) = 3.5X
The scale factor EC/BC=x/3.5x=2/7
EC/BC=ED/BA=2/7
BA=7/2×63 in
The height of the tree = 220.5 inches. This is equal 18 feet and 4.5 inches.
