Answer:
considering the above 45*
to make the line that would represent 180*
180 - 45 = 135
(2 / 135 - 5)
62.5
62.5 is your answer
Step-by-step explanation:
The possible problems of using graphs to find roots are:
- Having complex roots.
- Having irrational roots.
<h3>How to find the roots of a quadratic function with a graph?</h3>
First, the roots of a quadratic function are the values of x such that:
a*x^2 + b*x + c = 0
To find the roots using a graph, we need to see at which values of x does the graph of the parabola intercepts the horizontal axis.
<h3>What are the possible problems with this method?</h3>
There are two, the first one is having irrational roots, in that case, an analytical or numerical approach will give us a better estimation of the roots. Finding irrational values by looking at the intercepts of the graph can be really hard, so in these cases using the graph to find the roots is not the best option.
The other problem is if we <u>don't have real roots</u>, this means that the graph never does intercept the horizontal axis. In these cases, we have complex roots, that only can be obtained if we solve the problem analytically.

Answer:
The answer is 596 square feet
Step-by-step explanation:
Recall the following formulas for area:
Rectangle of lenght l and width w: 
Triangle of base b and height h: 
In our case, since we have a pyramid with rectangular base, so we have 5 sides: the rectangular base and 4 triangles, that are grouped in two pairs of identicall triangles. Let us call the triangles T1 and T2. Then the total surface area is given by
surface area = Area of the base + 2*Area of T1 + 2* Area of T2
The base is a rectangle of lenght 16 and width 12, so the area is 16*12 = 192.
T1 is a triangle of base 16 and height 14, so it has area 16*14/2 = 112.
T2 is a triangle of base 12 and height 15, so it has area 15*12/2 = 90.
So the total area is
Area = 192+2*112+2*90 = 596.
