Answer:

The value of x is 8, and m<ST = 48 degrees.

Step-by-step explanation:

With the given information, we know the worth of each angle.  To solve it, an equation must be made.  

RS (part) + RT (part)  = ST (whole)

Should look like this: 5x - 13 + 2x + 5 = 3x + 24.

Then solve the equation.

First, add up all that has in common:

Should look like: 7x - 8 = 3x + 24

Then move 3x from the right to the left by subtraction.  

Should look like: 4x - 8 = 24

Next, move the 8 to the other side by addition.

Should look like: 4x = 32

Finally, to find what the value of x is, divide 4 on both sides.  

You should get an answer of x = 8.

To find the measurement of ST, replace the x in 3x + 24.  

3(8) + 24 = 48.

m<ST = 48 degrees.

If <br> B is the midpoint of AC, AB=x+6 and AC=5x-6, then what is BC?
nikklg [1K]

If B is the midpoint of AC, then AB=BC. It is also BC=AC-AB

AB = x + 6

AC = 5x - 6

BC = (5x - 6) - (x + 6)

We can kinda use distributive property, like this:

BC = 5x - 6 -x - 6

Combine like terms:

BC = 4x - 12

To verify, we can add AB and BC to see if their sum is equal to AC.

(x + 6) + (4x - 12) = 5x - 6

If we are correct, this equation will be true.

x + 6 + 4x - 12 = 5x - 6

Combine like terms:

6 + 5x - 12 = 5x - 6

5x - 6 = 5x - 6

It's correct!

BC = 4x - 12. Final Answer.

Let me know if you have any questions about this! :)

How do I simplify the following to "a+bi" form: (1+2i)^3
damaskus [11]

Answer:

Expand it.

(1+2i)^3 is equal to (1+2i)(1+2i)(1+2i).

Multiply everything out (being sure to multiply <em>every</em> term. (1+2i) * (1+2i) = 1+2i+2i+4i^2.

i is the square root of negative one, so i^2 is just -1. 1+2i+2i-4 is what you get from the first two, so now simplify that:

1-4 + 2i+2i = (-3+4i) and now multiply that by (1+2i):

(-3+4i) * (1+2i) = -3 - 6i +4i +8i^2.

Simplify again, and the answer is: -11-2i

Step-by-step explanation:

I hope this helps - really my only tip is don't spend time thinking about what i is, that just hurts your brain. Just remember that i^2 is equal to negative one, and treat it like regular multiplication and you will be fine.
