Ontario ate a triangular jumbo pizza slice with a perimeter of 160 cm. The two shorter sides of the triangle what equal in length and the longest side is 10 cm longer than the either side. How long was each side of the slice? Use the equation to solve the problem. Set the variable as x.

Answer 1

Let x be the length of the two shorter sides of the triangle.

Therefore, the length of the longest side would be x + 10.

Since the perimeter of the triangle is the sum of all three sides, we can set up an equation:

x + x + x + 10 = 160

3x + 10 = 160

3x = 150

x = 50

Therefore, each of the two shorter sides is 50 cm in length, and the longest side is 60 cm in length.
