13. side a = 330, side b = 180
      angle x = 180 - 25 = 155

side x = x^2 = a^2 + b^2 - 2ab*cos(x)

330^2 + 180^2 - 2(330)(180)*cos(155) = 498.6 = 499 miles

Without graphing, classify the following system as independent, dependent, or inconsistent. y=-3x+4 and 6x+2y=8
forsale [732]

Answer:

Dependent

Step-by-step explanation:

y=-3x+4 and 6x+2y=8

Lets solve the second equation for y and then substitute it in first equation

6x+2y=8

Subtract 6x on both sides

2y=-6x+8

Divide by 2 on both sides

y=-3x+4

Now we plug it in first equation for y

-3x+4=-3x+4

Add 3x on both sides

4=4

Both sides are same, they are equal. the system has infinite solutions.

They are said to be dependent

Identifying Properties Which property is shown? If m∠ABC = m∠CBD, then m∠CBD = m∠ABC reflexive property substitution property sy
Burka [1]

Answer:

Symmetric property

Step-by-step explanation:

In this question, we are given a set of options to choose the correct answer from which gives the definition of the property in the question.

The correct answer here is the symmetric property. So why is this correct?

In proper terms, we refer to this property as the symmetric property of congruence.

It is a way of referring to the fact that when writing the way two congruent angles are equal to each other by the property of congruence, we can move in either of the two directions.

Either way we write, we are absolutely correct to indicate that both angles are equal due to the property of congruence.
