A and B are vertical angles. If m A = (3x+3)° and m B= (4x-8)°, then find the value of x.

iogann1982 [59]

Answer: x=11

Step-by-step explanation:

First, since angle A and angle B are vertical angles, that means that they are congruent. If they are congruent, then the m of angle A equals the measure of angle B. So, (3x+3)=(4x-8). Simplify using algebra so that in the end, you will find that x=11.

3x+3=4x-8

3=x-8

11=x

LuckyWell [14K]

Answer:

Independent variable

Step-by-step explanation:

Independent variable :

An independent variable is a variable that speaks to an amount that is being controlled in a trial. A needy variable speaks to an amount whose worth relies upon those controls.

It is the variable in a equation that may have its worth unreservedly picked without thinking about estimations of some other variable.

For example :

In equation $y=5x+3$ , x is an independent variable
