One side of the triangle is 19 cm, which is 14 cm less than the other side and 59 cm less than the perimeter. Find a third party.

1. Calculate the length of the second side of the triangle, adding 14 cm to the length of the first side:
19 + 14 = 33.
2. Now we find the sum of two sides, the length of which we know:
19 + 33 = 52.
3. Calculate the perimeter, which is 59 cm longer than the first side:
19 + 59 = 78.
4. Find the length of the third side, for this we subtract the total length of the known sides from the number found in the previous action:
78 – 52 = 26.
Answer: 26 cm.
