QuestionHow many isosceles triangles with whole-number sides have a perimeter of 18? (Hint: 5,5,8 is the smallest.) a. 1 b. 2 c. 3 d. 4

Studdy Solution
We have now tried all possible values of aa from1 to9, and found valid solutions (5,5,8), (6,6,6), (7,7,), and (8,8,).
Therefore, there are different isosceles triangles that have sides that are whole-number lengths and that had a perimeter of18.
So, the answer is (d).
