Which of the following possibilities will form a triangle? Side=15cm, side= 7cm, side=9cm
side=15cm, side=7cm, side=9cm
side=14cm, side=6cm, side= 7cm
side=14cm, side =6cm, side=8cm

just find the gcf and solve the gcf's until you get each answer i have a really good feeling somethings missing xd (like the dimensions of the fence) *cough *cough *hint *hint

step-by-step explanation:

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

55 degrees because 55+55=110 degrees
