Let the number be x
reciprocal=1/x
2 more the reciprocal=1/2+x
but 1/2+x=3(1/x)
1/2+x=3/x
x=6+3x
x=-2
Answer:
5.5 = x

Solution:
Given triangle is a right triangle.
Base = 5, Hypotenuse = 13, Height = ?
Height (h) = opposite
<em>In right triangle, square of the hypotenuse is equal to the sum of the squares of the other two sides.</em>



Taking square root on both sides.
h = 12












The simplified ratio is 3:4
