Answer:
Step-by-step explanation:
Let the angle between and 150° be = b°
[ Forming a linear pair of angles]
Solving for by subtracting both sides by 150.
∴
[Angle lying on a straight line add up to 180]
Plugging in
Solving for by
subtracting both sides by 80.
then dividing both sides by 2.
So 4/30 = 6/x
Solve for x
4x=180
X=45

The mean is calculated by adding all the data values together, and then dividing the sum by the number of data values.
12+10+11+13+14+10+12+13+14=109
109÷9≈12.1
<u>The mean of the data set is about 12.1.</u>
25 is the greatest common factor of 75 and 25. 3 x 25 = 75.
