Question 636139: Hello im a bit itchy about this question : Three sides of a triangle are are 2, 4, and 5. the two smallest size of a similar triangle are 6 and 12. find the measure of the missing side.
Do I just do this: 6^2+12^2= c^2 and solve? But then what was the point of the other triangle and it's side?
Thanks~

Hi,
Three sides of a triangle are are 2, 4, and 5
the two smallest size of a similar triangle are 6 and 12
2%2A3+=+6 and 4%2A3+=+12, 5%2A3+=+15
