Yo sup??
The two triangles are similar by AAA property ie
Angle Angle Angle property
Let us name the two triangles as ABC and DEF
By observing the figure
mB=mE=90   (right angled triangle)
mA=mD   (parallel lines property)
mC=mF    (parallel lines property)
Therefore by AAA the two triangles are similar .
The diagram is given below.

Answer:
a)
Mean = sum of all numbers in dataset / total number in dataset
Mean = 8130/15 = 542
Median:
The median is also the number that is halfway into the set.
For median, we need to sort the data and then find the middle number which in our case is 546. Below is the sorted data
486  516 523  523  529  534  538  546  548  551  552  558  566  574  586
Standard Deviation (SD).  Here X represents dataset and N= count of numbers in data
As per the SD formula, which is Sqrt ( sum (X_i - Meanx(X))/(N-1))
SD= 25.082
2) Formula for coefficient of skewness using Pearson's method (using median) is, 
SK = 3* ( Mean (X) - Median(X))/(Standard Deviation) =  3*(542-546)/25.082 = -0.325
3) coefficient of skewness using the software method is also same which is -0.325
