1st, find the mean of all values. 1+2+3+4=10 10/4=2.5 The mean is 2.5.
2nd, find the distance of each value from the mean. So 2.5-1=1.5; the distance between 1 and 2.5 is 1.5. Repeat it for all of them, and you get 1.5, .5, .5, and 1.5.
3rd, you take each distance and find the mean. 1.5+.5+.5+1.5=4 4/4=1 The mean deviation is 1.
Answer:
The angle between the building and the ladder 6.9°
Step-by-step explanation:
Given data
AB = 50 ft = length of the building
BC = 6 ft
= Angle between the ladder & building
From Δ ABC
6.9°
This is the angle between the building and the ladder.
The sum of a straight angle is 180°
So 77+x=180
Subtract 77 from both sides and the equation is
x=77
The measure of the other angle is 77°
Answer:
0
Step-by-step explanation:
Anything times 0 is 0.
Answer: Two angles are called complementary when their measures add to 90 degrees. Two angles are called supplementary when their measures add up to 180 degrees.
