We know the opposite and adjacent sides of angle B, so we can use the inverse tangent to solve for its value.
tan(B)^-1 = 3/4
B = 64.4 degrees
Answer:
The nail would be 30 feet above the ground in 10 years.
Step-by-step explanation:
We are given the following in the question:
Height of nail = 10 feet.
The tree grows taller at a rate of 2 feet per year.
Thus, the height of nail can be represented by a linear function:

where t is the number of years.
We have to find the height of nail in 10 years.
Putting t = 10, we get,

Thus, the nail would be 30 feet above the ground in 10 years.
Answer:
50 cubic meters
Step-by-step explanation:
5 squared times 6 divided by 3
Formula is Base edge times height divided by 3
The area of a circle is defined as Pi R^2
Since we only have the diameter and Pi, we need to solve for the radius.
The radius is 1/2 of the diameter, so divide 6 by 2 to get our radius.
6 / 2 = 3
Our radius is 3.
Now let's plug in our formula.
A = 3.14 x 3^2
3 x 3 = 9
9 x 3.14 = 28.26
Your area is 28.26 units ^2
I hope this helps!
