Part A. Set up the equation. Part B. The value of n is Analyze the figure below and solve for n. 5n - 12 = 90 5n - 12 = 133 5n - 12 = 43 5n - 12 + 90 + 43 = 180 Part A. Set up the equation. Part B. The value of n is Analyze the figure below and solve for n. 6n - 5 = 115 115 + 6n - 5 = 180 6n - 5 = 25 6n - 5 + 90 + 25 = 180 Part A. Set up the equation. Part B. The value of n is Analyze the figure below and solve for n. 2n + 15 = 37 2n + 15 + 37= 180 2n + 15 = 127 2n + 15 + 37 + 90 = 180 a a a |
