Answer:

\Huge \boxed{5x - 19}

\rule[225]{225}{2}

Step-by-step explanation:

A ——— B ——— C

AC = 8x - 20

AB = 3x - 1

BC = AC - AB

BC = (8x - 20) - (3x - 1)

Distributing negative sign.

BC = 8x - 20 - 3x + 1

Combining like terms.

BC = 5x - 19

\rule[225]{225}{2}

Answer:

x=17

Step-by-step explanation:

Since these angles are supplementary, they will add up to 180 degrees, so you can set up the equation like this:

4x+8+104=180

First, combine like terms:

4x+(8+104)=180

4x+112=180

Next, subtract 112 from both sides:

4x+112(-112)=180(-112)

4x=68

Then, divide each side by 4:

4x(/4)=68(/4)

x=17

17 is your answer.
