Question

Triangle E has a perimeter of 125 inches. Two of

its side lengths are 26 inches and 55 inches.
What is its missing side length?

Answer 1

44 inches

Explanation:

perimeter of triangle = length of side 1 + length of side 2 + length of side 3

length of side 1 = 26

length of side 2 = 55

125 = 26 + 55 + length of side 3 = 81 + length of side 3

subtract 81 from both sides to get the length of side 3

length of side 3 = 44 inches
