Answer:
The length of the sides are 9 units, 18 units and 11 units
Step-by-step explanation:
Let
x ----> one side of the triangle
y ----> the longest side of the triangle
z ----> the third side of the triangle
we know that
The perimeter of triangle is equal to
we have
so
----> equation A
-----> equation B
----> equation C
substitute equation B and equation C in equation A
solve for y
<em>Find the value of x</em>
--->
<em>Find the value of z</em>
---->
therefore
The length of the sides are 9 units, 18 units and 11 units
ANSWER
EXPLANATION
If y varies directly with x, we write the mathematical statement;
When we introduce the constant of proportionality k, then we write the equation,
If y is 2.5 when x is 5,then we have;
The equation of variation then becomes;
when x=14,
