Ashley has three hog panels. Panel A is 8 feet long, panel B is 3 feet long, and panel C is 7 feet long. If the full length of each panel is used, can she build a triangular pen to hold her pet pig?
A.
yes, 8 - 3 > 7
B.
no, 3 + 7 < 8
C.
no, 8 - 7 < 3
D.
yes, 3 + 7 > 8
D. yes, 3 + 7 > 8
By using panels B and C, Ashley can create a triangle with sides of length 3, 7, and 8, which satisfies the triangle inequality theorem where the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
