Step-by-step explanation:
13.
Given


Required
Determine the distance between M and S
Distance (D) is calculated using:

Where








<em>Hence, the distance between M and S is 18 units</em>
<em></em>
14.
The coordinate of S and P are not given,
So, I'll just use (x,y) for P
i.e.

Required
Determine the coordinates of S
If S is 6 units above P, then the coordinates of S is

<em>i.e. we add the units to the y coordinate of P.</em>
Let cost price be x
according to question
x + 40% of x = 280
x+ 0.4x=280
1.4x=280
x=200
this 200 is the store cost or cost price for store
30%of 200= 60
according to question,
cost for employee= 200-60= 140
One rotation has 360 degrees. Since regular Pentagon has 5 sides and each of them takes 360/5=72 degrees when looked from center, if we rotate regular Pentagon by 72 degrees we will get same shape as we started from.
Therefore answer is 72 degrees.
