PART C. Find the measures of the following. m∠ABC = m∠BAC = PART B. Find the value of x. m∠BCA = m∠BCD = PART A. Set up the equation. 4x + 4 + 7x + 32 = 5x + 2 4x + 4 + 5x + 2 +7x + 32 = 180 4x + 4 + 5x + 2 = 7x + 32 4x + 4 + 5x - 2 +7x + 32 = 180 PART C. Find the measures of the following. m∠ABC = m∠BAC = PART B. Find the value of x. m∠BCA = m∠BCD = 6x + 5 - 9x + 1 = 13x + 22 6x + 5 + 9x + 1 +13x + 22= 180 6x + 5 + 9x + 1 = 13x + 22 PART A. Set up the equation. 6x + 5 + 9x + 1 = 180 r r r |
