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
