The length of the first side of the triangle is 34cm, the second is 29cm, and the length of the third side is 30cm

The length of the first side of the triangle is 34cm, the second is 29cm, and the length of the third side is 30cm less than the sum of the lengths of the first two sides. 1) Find the length of the third side of the triangle. 2) find the perimeter of the triangle.

1 side of the triangle is 34 cm;
2 side of the triangle is 29 cm;
3 side of the triangle is (34 + 29) -30 = 33 cm
The perimeter of a triangle is the sum of the lengths of all sides
34 + 29 + 33 = 96 cm
Answer: 1) 33cm; 2) 96cm
