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.
A. 5.4 ftx>13 ft

Answer 1

let's assume 3.8 and 9.2 are the shorter than the third
so we have:
\[3.8+9.2>x\]
where I'm calling x the measurement of the third side



let's assume 3.8 and x are the shorter than the side with measurement 9.2
so we would have:
\[3.8+x>9.2\]


(and 3.8 cannot be the longest side since 9.2>3.8)




anyways solve the two inequalities
