The ratio of the sides of a triangle is 3:5:10. If the perimeter of the triangle is 90 centimeters, what is the length of each side? and what kind of proportion?

You can just make the sides of the triangle 3x, 5x, and 6x, where x is the scaling factor that will bring the total up to 98. Then, simply add and solve for x:

You can just make the sides of the triangle 3x, 5x, and 6x, where x is the scaling factor that will bring the total up to 98. Then, simply add and solve for x: 3x+5x+6x=98

You can just make the sides of the triangle 3x, 5x, and 6x, where x is the scaling factor that will bring the total up to 98. Then, simply add and solve for x: 3x+5x+6x=9814x=98

You can just make the sides of the triangle 3x, 5x, and 6x, where x is the scaling factor that will bring the total up to 98. Then, simply add and solve for x: 3x+5x+6x=9814x=98x=7

You can just make the sides of the triangle 3x, 5x, and 6x, where x is the scaling factor that will bring the total up to 98. Then, simply add and solve for x: 3x+5x+6x=9814x=98x=7 Your shortest side is the 3x, so its length would be 3*7 or 21.
