104 is a multiple of the following numbers
1,2,4,8,13,26,52,104
arranging them into multiplication form,
1*104, 2*52, 4*26, and 8*13
they all satisfy the second rule but 8*13 is the only one that satisfies the first rule (13-8= 5 and 13*8 =104)

Answer:
==============
Imagine the height of the triangle is h, which is perpendicular to 15 m side.
The area is:
Use this formula and given values and find the value of h:
- 60 = 15h/2
- h = 60*2/15
- h = 8 m
Since h is opposite to 30° angle and x is the hypotenuse of the formed right triangle, we'll use the property of 30°x60°x90° triangle.
- <em>Hypotenuse is twice the length of the side opposite to 30° angle.</em>
In our case h is opposite to 30° angle, therefore we have:
