PART C. Find the measures of each angle. m∠ABC = m∠BAC = m∠ACB = m∠BCD = PART A. Set up the equation. 3x-12 + 4x + 8 + 4x + 8 = 180 3x-12 + 4x + 8 = 180 3x-12 = 4x + 8 PART B. The value of x is PART C. Find the measures of each angle. m∠ABC = m∠BAC = m∠ACB = m∠BCD = PART A. Set up the equation. 6x - 12 + 5x + 8 + 5x + 8 = 180 6x - 12 + 5x + 8 = 180 6x - 12 = 5x + 8 PART B. The value of x is a a a |
