The first side of the triangle = 23 dm, the second 5 dm. less, and the third is less than the perimeter by 41 dm. Find what the longest side of the triangle is if it is known that the first side is 580 cm less than the perimeter.
1) the first side is 23 in.
2) the second side is 23 – 5 = 18 dm
3) the perimeter is 23 dm + 580 cm = 230 cm + 580 cm = 81 cm = 81 dm
4) the third party is 81 dm – 41 dm = 40 dm
answer: 40 dm
