Find the midpoint of the line segment with the endpoints A and B.

zavuch27 [327]

Answer:

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

$M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )\\$

From the question we have

$m = ( \frac{2 + 10}{2} \: , \: \frac{6 + 8}{2} ) \\ = (\frac{12}{2} \: , \: \frac{14}{2} ) \: \: \: \: \: \: \:$

We have the final answer as

Which of the following correctly justifies statement 4 of the two-column proof?

slavikrds [6]

Answer:

D.Transitive property of equality

Step-by-step explanation:

We are given that segment JK is parallel to segment LM

We have to prove $\angle 3=\angle 6$

We have to find which option correctly justifies the statement 4 of the two - column proof.

1.Statement : JK is parallel to segment LM

Reason: Given

2. $\angle 7\cong \angle 6$

Reason: Vertical angles theorem

3. $\angle 3\cong \angle 7$

Reason:Corresponding angles theorem

4. $\angle 3\cong \angle 6$

Reason: Transitive property of equality.

If a=b and b=c then a=c

Hence, option D is true.

How to know how to do percent of change

IgorC [24]

Work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100. % increase = Increase ÷ Original Number × 100. If your answer is a negative number then this is a percentage decrease.
