Answer:
the length of the first side of the triangle is
the length of the second side of the triangle is
the length of the third side of the triangle is
Step-by-step explanation:
Let
x-----> the length of the first side of a triangle
y----> the length of the second side of a triangle
z---> the length of the third side of a triangle
we know that
-----> equation A
-----> equation B
The perimeter of the triangle is equal to
so
-----> equation C
substitute equation A and equation B in equation C
solve for x
Find the value of each side
the first side of a triangle is x
the second side of a triangle is y
the third side of a triangle is z
