Answer:
The example is telling you to first add up each number then divide by the amount of numbers that are present in the set. There are four in this example.
Secondly the difference between each data point will differ from each number. Basically subtract the sum from each number. Which is 5 in this case. But if its negative flip it to a positive.
Then add up each absolute value and divide by 4 twice.
Given :
Two vertical buildings 57 meters apart are 158 meters and 237 meters high.
To Find :
The angle of elevation from the top of the shorter building to the top of the taller building.
Solution :
Distance between height of building, h = 237 - 158 = 79 m.
Distance between these building , d = 57 m.
Now,

Therefore, the angle of elevation from the top of the shorter building to the top of the taller building is 54.19°.
Hence, this is the required solution.

Answer:
Step-by-step explanation:
12x+3y= 15
12x= -3y+15
divide both sides by 12 and you get
x= -3/12y+15/12
simplifying:
x=-1/4+5/4
