Question

Each of the equal sides of an isosceles triangle is 5 times the third side. The perimeter of the triangle is 121 inches. Find the sides of the triangle.

Answer 1

The third side is 11 inches

the 2 equal sides are 55 inches each side.

Explanation:

X + 2(5x) = 121

x + 10x = 121

11x = 121

x = 121/11

x = 11

Answer 2

Answer: The small side is 11, and the other two are 55, 55,

Explanation:

So the perimeter adds up to 121 inches.

we know that two of the sides are 5x the 3rd side while being congruent.

11 times 5=55. 55 times 2=110. 110+11=121
