Answer:

Step-by-step explanation:
Given
See attachment for graph
Required
The equation of best fit
First, we pick two corresponding points on the graph,
We have:


Calculate slope (m)

This gives:



The equation is the calculated using:

This gives

Open bracket


70? Is this a trick question?
The volume is given by:
V = A * H
Where,
A: area of the base
H: prism height
Clearing the area we have:
A = V / H
A = 276/10
A = 27.6 feet ^ 2
The area of the base is given by:
A = (1/2) * (b) * (h)
Where,
b: base of the triangle
h: height of the triangle
Clearing b we have:
b = (2 * A) / (h)
Substituting values:
b = (2 * 27.6) / (6.9)
b = 8 feet
Answer:
the base length is:
b = 8 feet
2 and three because the have the same length and all sides are the same
Yes, it would be 78 degrees.
These are vertical angles, which always are the same measure. When a lone intersects another, there is always 2 pairs of vertical angles.
Hope this helps! :D
Keep up the good work, you're correct!
