A triangle has two sides of length 7 and 9. What value could the length of the third side be
let us have point A be (0,0)
B (0,7)
C (9,0)
so AB=7, AC=9, and BC= ?
distance BC = sqrt((9-0)^2+(0-7)^2)=sqrt(9^2+(-7)^2)=sqrt(81+49)=sqrt(130)
BC=sqrt(130)
BC=11.4018 rounded to 4 places

To find the range of the third side find BIG + SMALL and then BIG - SMALL
BIG - SMALL = 2
BIG + SMALL = 16
So,
2 < third side < 16.
