12.4×3.80=47.12
4×1.99=7.96
2×1.55=3.10
All will give , 58.18
so you should write in answer,
I am not agree because the total cost is different from the total given cost !!
We have a triangle, when:
hypotenuse=slant height=20 ft
opposite side=height of the tree=?
angle formed by the tree with the ground=72º
sin Ф=opposite/ hypotenuse ⇒ opposite=(hypotenuse)(sin Ф)
In this case:
oppssite=20 ft /sin 72º=19.021...≈19
Answer: the heigth of the tree is 19 ft.
The answer is <span>y= (x-3)^2 + 9
I hope this helps</span>
