Question 310985
an isosceles triangle is a triangle with 2 congruent sides. if the third side is three times the length of the congruent side and the perimeter is 75 find the length
----------------
You can do the math:
s + s + 3s = 75
s = 15
---------
But that makes the sides 15, 15 and 45.  It's not possible to make those into a triangle.
