Question 14 • WV-Algebra I CR
The equal sides have total length 15.7 − b, so the triangle inequality requires 15.7 − b > b. Solving gives b < 7.85, and a side length must also be positive, so b > 0. Thus 0.5 in. and 2 in. are possible; 7.9 in. is too long, and −2 in. and 0 in. cannot be side lengths.
