> The sides of a triangle are in the ratio 5:12:13.
What is the length of each side of the triangle if the perimeter of the triangle is 15 in.
:
Let x = the multiplier of each ratio value to achieve this perimeter:
:
5x + 12x + 13x = 15
30x = 15
x = 15%2F30
x = .5
:
The dimensions:
.5(5) = 2.5
.5(12) = 6
.5(13) = 6.5
;
:
Check solution: 2.5 + 6 + 6.5 = 15
:
Statement.
multiply each of the ratio values by one half to get a perimeter of 15
