Answer:
The answer is below
Step-by-step explanation:
The slope of a line (m) is given by:

Two lines are parallel if they have the same slope and perpendicular if the product of their slope is -1.
1)

Since the product of their slope is -1, they are perpendicular
2)

Since the slope is not the same or product of their slope is not -1, they are neither parallel or perpendicular
3)

Since the slopes are the same, they are parallel
4)

Since the slopes are the same, they are parallel
5)

Since the product of their slope is -1, they are perpendicular
Answer:
Step-by-step explanation:
the balloon starts at (10, 0 )
it ends at 16,0)
in the middle it's at between 10 and 16 , so say about 13, where it reaches 27
so in the middle it's (13,27)
so ( 11, 9)
(12, 18)
got 13
(14, 18)
(15, 9)
got 16
:P
Pick out the like terms. 6x^2 (which equals 36x), 11x, 2x^2 (which equals 4x), -17x.
36+11+4= 51, -17= 34x
-3+-4= -7
The simplified expression would be 34x+-7.
(This could be wrong though, I'm sorry if it is ^^)
The length of the triangle will be equal to 2.7.
<h3>How to calculate the length?</h3>
It should be noted that that sin will be the opposite divided by the hypothenuse.
The measure of angle L is 20°.
This will be:
sin 20 = LN/8
NM = 8 sin 20
NM = 2.7
In conclusion, NM is 2.7.
