Third side unknown Write an equation and solve it to find the length of the longest side of the triangle. 128x + 150 = 450; x = 2.34 cm x + 278 = 450; x = 172 cm 2x + 278 = 450; x = 86 cm 150x + 128 = 450; x = 2.15 cm

Answer 1

128x + 150 = 450; x = 2.34 cm x + 278 = 450; x = 172 cm 2x + 278 = 450; x = 86 cm 150x + 128 = 450; x = 2.15 cm. All these answer add up to wrong you are completely wrong
