The height of the tree is 9 meters
<h3>What is angle of elevation?</h3>
This is the angle the line of sight makes with the horizontal.
Analysis:
The line of sight , the shadow length and height of tree form right angled triangle.
Let the height of tree be h
so that, tan 24 = h/20
h = 20 tan 24
h = 20(0.445) = 8.9m = 9m
In conclusion, the height of the tree is 9m.

Answer:
Future value is $1543.12
Step-by-step explanation:
From the question, present value = $200, rate = 10%, years = 6.
So that future value of ordinary annuity can be calculated by,
FV = ![\frac{A{[(1+r)^{n} - 1]}}{r}](https://tex.z-dn.net/?f=%5Cfrac%7BA%7B%5B%281%2Br%29%5E%7Bn%7D%20-%201%5D%7D%7D%7Br%7D)
where: FV is the future value, A is the annuity, r is the rate, and n is the number of years.
FV = ![\frac{200[(1+0.1)^{6}-1] }{0.1}](https://tex.z-dn.net/?f=%5Cfrac%7B200%5B%281%2B0.1%29%5E%7B6%7D-1%5D%20%7D%7B0.1%7D)
= ![\frac{200[1.1^{6}- 1] }{0.1}](https://tex.z-dn.net/?f=%5Cfrac%7B200%5B1.1%5E%7B6%7D-%201%5D%20%7D%7B0.1%7D)
= ![\frac{200*0.771561}{0.1}](https://tex.z-dn.net/?f=%5Cfrac%7B200%2A0.771561%7D%7B0.1%7D)
= ![\frac{154.3122}{0.1}](https://tex.z-dn.net/?f=%5Cfrac%7B154.3122%7D%7B0.1%7D)
FV = $1543.122
The future value of the ordinary annuity is $1543.12.
is this a qeston from homework?
Answer:
(x+9)(x+2)
Step-by-step explanation:
x+11x+18
x 9
x 2
9+2=11
False; 4cd cannot be added with 8c because their variables don’t match up therefore meaning they cannot be added together.
