HELP DUE SOON!<br><br> x = ?? degrees
rjkz [21]

Answer:

Step-by-step explanation:

Tricky. Very neat.

You are missing the minor arcAC and you need it, but don't fret. It can be found.

The formula for this is x = 1/2(Major Arc(235) - Minor Arc(see below) )

The minor arc is the supplement of x.

The minor arc is also equal to the the central angle

So the minor arc is 180 - x

x = 1/2 (235 - (180 - x) )                    Remove the inside  brackets

x = 1/2 (55  + x )                               Remove the remaining brackets

x = 1/2 *55 + 1/2x                             Subtract 1/2x from both sides

1/2 x = 27.5                                      Multiply both sides by 2

x = 55

I'm really not sure how to go about solving this algebraic equation, please help! .513 = (2x)^2 / (.05-x)
LiRa [457]
Let's set it up like this:
0.513=\frac{\left(2x\right)^2}{\left(0.05-x\right)}
Multiply both sides by 0.05-x
0.513\left(0.05-x\right)=\frac{\left(2x\right)^2}{0.05-x}\left(0.05-x\right)
0.513\left(0.05-x\right)=4x^2
We are then going to use the distributive property. Since we also know that the opposite of an number that is squared is the square root, we can also apply that. We would be left with something like this:
x=-\frac{0.513+\sqrt{0.673569}}{8},\:x=\frac{\sqrt{0.673569}-0.513}{8}
The variable x can be both positive or negative.
We have found successfully our answer.

Let me know if you have any questions regarding this problem!
Thanks!
