an = 11 + 4(n-1)
an = 11 + 4n - 4
an = 4n + 7
Area= (length)(width)
divide by (length) on both sides.
(width)= (area)/(length).
Your best bet is treating area, length, and width as numbers. You can plug in numbers and take them out in the end. Hope this helps!
If you would like to solve 2 * (7 - x) = 3 * (x + 3), you can do this using the following steps:
2 * (7 - x) = 3 * (x + 3<span>)
</span>2 * 7 - 2 * x = 3 * x + 3 * 3
14 - 2 * x = 3 * x + 9
14 - 9 = 3 * x + 2 * x
5 = 5 * x
x = 1
The correct result would be x = 1.
Answer: Circumcenter
Step-by-step explanation: The circumcenter is the point where all perpendicular bisectors of a triangle meet. The 3 perpendicular bisectors of the 3 sides of the triangle meet at the point which is labeled in this triangle as H.
Answer: Height of tree = 26 ft
Make a triangle ABC with 40 degrees angle. The shadow is the base of the triangle equals 31 feet.
Base = AC = 31
Perpendicular = CB = ?
Hypotenuse = AB
Using trigonometric equation
tan 40 (deg) = CB / AC
CB = Tan 40 x AC
CB = 0.83909 x 31
CB = 26.011
Thus the height of the tree = 26 ft
