If you solve it, the answer will be
C= 4.80
Seeing as its supposed to be a whole number, you will round up, so it will be 5
Can someone explain by steps on how to do this
1 answer:
Answer:
8
Step-by-step explanation:
This is a special right triangle with angle measures 90-60-30 degrees
The side lengths are like the following :
The side length that sees 90 degrees is represented with x
The side length that sees 60 degrees is represented with x
The side length that sees 30 degrees is represented with 2x
the side that sees 90 degrees is given as 16 so x = 8 and so a = 8

To solve for x in terms of b, simply treat b as a number, and solve for x as usual: first of all, we expand the left hand side:
Subtract 10 from both sides:
Divide both sides by -2b:
This means that in particular, if we set , we have
Answer:
Step-by-step explanation:
We are given that the graph of the equation:
Passes through the three points (0, 5), (1, 10), and (2, 19).
And we want to find the value of (<em>a</em> + <em>b</em> + <em>c</em>).
First, since the graph passes through (0, 5), its <em>y-</em>intercept or <em>c</em> is 5. Hence:
Next, since the graph passes through (1, 10), when <em>x</em> = 1, <em>y</em> = 10. Substitute:
Simplify:
The point (2, 19) tells us that when <em>x</em> = 2, <em>y</em> = 19. Substitute:
Simplify:
This yields a system of equations:
Solve the system. We can do so using elimination (or any other method you prefer). Multiply the first equation by negative two:
Add the two equations together:
Combine like terms:
Hence:
Using the first equation:
Therefore, our equation is:
Thus, the value of (<em>a</em> + <em>b</em> + <em>c</em>) will be:
