Accepted Solution

A:

Answer:Please look down belowStep-by-step explanation:β 1 + 69 + 47 = 180 (because straight line)β 1 = 180 - 116β 1 = 64β 2 + β 1 + 63 = 180 (because triangle)β 2 + 64 + 63 = 180β 2 = 180 - 127β 2 = 53β 3 + β 1 = 180 (because straight line)β 3 + 64 = 180β 3 = 116β 5 = β 4 (given)β 5 + β 4 + β 3 = 180Denote β 5 and β 4 as x, so 2x2x + β 3 = 1802x + 116 = 1802x = 64x = 32β 5 = 32, β 4 = 32β 6 + 136 = 180 (because straight line)β 6 = 44β 7 + β 6 + 47 = 180 (because triangle)β 7 + 44 + 47 = 180β 7 = 180 - 91β 7 = 89
