Question

Two equal sides of an isosceles triangle are 4m less than 3 times the third side.Find the dimensions of the triangle, if the perimeter is 55m.

Answer 1

Here is your answer > >
Let the third side be x
Equal angles will be 3x-4
Perimeter=55m
x+3x-4+3x-4=55
7x-8=55
7x=63
x=9m
Equal sides will be 3×9-4=23m
hence all sides are 9m,23m,23m
