The perimeter of a triangle is 85 centimeters. If two sides are equally long and the third side is 10 centimeters longer than the others, find the lengths of the three sides. The length of each of the two equally long sides is and the length of the longer side is

Step 1
Therefore, the length of the third side is x + 10. The perimeter of a triangle is the sum of the lengths of all its sides. So, we can write the equation: x + x + (x + 10) = 85 This simplifies to: 3x + 10 = 85 Subtract 10 from both sides: 3x = 75 Show more…
