two sides of a triangle are 11 centemeter and 9 centemeter.if the perimeter of the triangle is 25 centemeter,what is the length of the third side of the triangle?
for the perimeter of the triangle, add all sides given that a, b, c are the sides of the triangle and p as perimeter the equation is as follows" p= a+b+c
therefore, given the sides and perimeter: 25= 11+9+x, solve for x, youll get:
