<span>(n-2)180=sum of the interior angles.
Where n=number of angles of a regular polygon.
(n-2)180=2340
divide both sides by 180 and get
n-2=13
add 2 to both sides and get
n=15 Therefore, this polygon has 15 sides.</span>
Step-by-step explanation:
m<6 + 63 = 180
m<6= 180-63
m<6= 117°
m<7 and m<3 are corresponding angles. They match
m<7= 63°
Let s be the slow train, and s+22 be the faster one. Then:
976/s+s+22=4
976=8s+88
8s=888
s=111 kph as the slower train
s+22=133 kph as the faster train

range is 31.5, variance is 161.3 and standard deviation is 12.7 for a sample of top 10 annual TV personalities.
Step-by-step explanation:
- Average is mid-point is the mid-point of the data but can skew....
- On the Left or Right is there are higher or lower values.
- Range is difference between maximum and minimum value of data.
- Variance, measure of variability of data but squared or mean deviation.
- Standard deviation is the most important variability.
- It helps in finding out variability with 3 sigma deviations.
- Standard deviation is square root of variance and each sigma explains...
- The data lieing between or within the extreme values.
