you will be using the tringle inequality theorm to solve this.
Steps:
1. Assign each value a variable (A, B, C)
A = 17 cm
B = 7 cm
C = 8 cm.
2. Fill in the variables in the equation, all 3 must be proven true for a triangle to be made though.
17 + 7 > 8 -- true
7 + 8 > 17 -- false
17 + 8> 7 -- true
3. Since not ALL 3 equations are true, the lengths can not be used to make a triangle.
