Explanation:
Based on the information given, we have a diagram with two sides labeled as 17 cm and X cm, and another side labeled as 15 cm.
To find the length of X, we can use the fact that the sum of the lengths of the sides of a triangle is equal to the perimeter.
Perimeter = 17 cm + X cm + 15 cm
The perimeter is the total distance around the triangle. Since we have three sides, the perimeter is the sum of the lengths of those sides.
However, it's important to note that we need additional information to solve for X. In a triangle, any two sides must be greater than the third side. So, we need to know the relationship between the lengths of the sides to determine the possible values for X.
