Question

If the perimeter of a triangle is 45 meters and two of the sides have lengths 17 meters and 19
meters, determine if the triangle is isosceles or not.

Answer 1

Answer:

Not isosceles

Step-by-step explanation:

45 - (17 + 19) = 9

9 is the side length which is not equal to either of the other sides so the triangle is scalene.
