PART B. The value of x is PART A. Set up the equation. Use the properties of angle bisectors to find the value of x. 5x + 17 = 3x - 7 5x - 7 + 3x + 17 = 180 5x - 7 = 3x + 17 5x - 7 = 3x + 17 = 90 PART B. The value of x is PART A. Set up the equation. Use the properties of angle bisectors to find the value of x. 7x - 45 = 2x + 15 7x - 45 + 2x + 15 = 180 7x + 15 = 2x - 45 7x - 45 + 2x + 15 = 90 PART B. The value of x is PART A. Set up the equation. Use the properties of angle bisectors to find the value of x. 8x + 22 = 5x - 33 8x - 33 + 5x + 12 = 180 8x - 33 = 5x + 12 8x - 33 + 5x + 12 = 90 w e |
