Thehypotenuse of the right triangle has a length of13.86, which is shorter than the third length ofthe other triangle, 14. So the SSS Inequalityallows us to conclude that x.90. In any triangle,an angle has measure less than 180, so we canwrite the compound inequality 90,x,180.19.Let dbe the distance between NewYork andAtlanta.5541399¬.d953¬.dor d ,9533991d¬.554d¬.155Therefore, 155 mi,d,953 mi.20.A; 318511, so 3, 8, 11 cannot be the sides of atriangle.Chapter 5 Standardized Test PracticePages 278–2791.D; there are 36 inches in a yard, so there are 362or 1296 square inches in a square yard.
