One side of a triangle is half the longest side. The third side is 10 meters less than the longest side. The perimeter is 45 meters. Find all three sides.

m (smallest value)
m
m (largest value)

Answer 1

2x+x+2x-10 = 45

2x+x+2x-10 = 55

5x = 55

X=11

Smallest - 11 m
Largest - 22 m
3rd side - 12 m
