Answer:
-3/2, -1
Step-by-step explanation:
Each coordinate contains one 
value and one 
value, 
.
If we work out the midpoint of each of these individually, it makes it much easier to find the midpoint of the line.
Let's take the values first. Our first value is -4 and our second value is 1. Imagine the integers between -4 and 1 laid out in a sequence:
If you take the middle value of this sequence, you get the midpoint of the values.
In this case, the middle is between values -2 and -1, leaving us with a midpoint of -1.5. This as a fraction is 
.
Now let's look at the values. Our first value is 2 and our second value is -4. Again, let's imagine those numbers laid out in a sequence:
Here, the middle of these values is -1, and this is the midpoint of the values.
So if we put these two values in a coordinate, we get the midpoint of the line.
In this case, we get 
.
Answer and Step-by-step explanation:
A pair of segments that are perpendicular to each other are the line segments:
KI (the letter i) and MJ.
This is because we see that at the intersection T, there a right angle symbol, which means that those 4 angles at the intersection are 90 degrees. When a line meets another line, and it is perpendicular to that line, they form 90 degrees.
So, those line segments are perpendicular.

Answer:
602
Step-by-step explanation:
Answer:
question (1)
height of building = 308 ft
question (2)
cos 67.11 = 7/18
Explanation:
question (1)
Taking a look at the triangle, we can see that it is a right-angled triangle. This means that we can apply the special trigonometric identities.
The one we will use here is:
tan Θ = opposite / adjacent
where:
Θ = 72
the opposite side is the height of the building
the adjacent side = 100 ft
Substitute to get the height as follows:
tan(72) = height / 100
height = tan(72)*100 = 307.76 which is approximately 308 ft
question (2):
We are given that:
cos Θ = 7/18
therefore:
Θ = cos^-1(7/18)
Θ = 67.114
approximating to the nearest tenth, we would find that:
Θ = 67.11°
Hope this helps :)
