Quadrilateral Review Packet Solve for x. Each figure is a parallelogram. 11x-5 | 105 11x 11x = 105 x = 10 9-7x | 105 7x+9 9-7x + 105 = 180 7x + 96 = 180 7x = 84 x = 12 9x | 130 4+130 130 = x + 130 x = 0 1+57x 123 + 57x = 180 57x = 57 x = 1 -2+18x | 88 18x -2 + 18x = 88 18x = 90 x = 5 155 | 3x+9 155 | 3x+9 3x+144 155 + 3x + 9 = 180 3x + 164 = 180 3x = 16 x = 12 Find the measurement indicated in each parallelogram. 8² + 20² = c² c = √464 c = 21.5 11² + 22² = c² c = √573 c = 23.9 20 20² + 20² = c² c = √800 c = 20√2 13.5 | 3 13.5 3² + 13.5² = c² c = √186.75 c = 13.7 Solve for x. Each figure is a parallelogram. 3x-1 | 14 14 14 = 3x - 1 15 = 3x x = 5 12) 9x | 9 9x 9 = 9x x = 1
