Mean is the average of a set of numbers that you are given.
To get the mean you need to add up all the numbers and divide that total number by the amount of numbers you had.
Cant see the picture can you zoom in?
x = 20, so the labeled angles are 80° and 100°.
So the labeled angles measure 80° and 100°.
The magnitude of the vector from the origin is 10
The unit vector in of the vector from the origin as (8/10, -6/10
<u>1.Finding the magnitude,</u>
we have the formula,
we have the values as a=8 and b=-6
Finding the magnitude we get,
<u>2.Finding the unit vector</u>
Divide by the magnitude
Unit vector: (8/10, -6/10)
x = 10
Since M is at the midpoint of TL , then
TM = ML , substitute values
2x + 8 = 3x - 2 ( subtract 2x from both sides )
8 = x - 2 ( add 2 to both sides )
10 = x , that is x = 10
