Question

Find the range for the measurement of the third side of a triangle, x, given the measures of the two sides: 3.8 ft and 9.2 ft.


5.4 ft < x < 13 ft

5.4ft x 13 ft

6 ft < x < 13

5.4 ft > x > 13 ft

Answer 1

the sum of the shorter sides of a triangle must be greater than the longest side

so if the side is the the longest it must be less than 13

if its a short side it must be greater than 9.2 - 3.8
