From the figure, we see that, 6c + a + b = 180 [Eq. 01] a = 2b and, 3c = b or, 6c = 2b Thus, Replacing the other values by the means of b in Eq. 01, we get, 2b + 2b + b = 180 or, 5b = 180 or, b = 36 Again, 6c + a + b = 180 or, 2b + a + b = 180 or, 3b + a =180 or, 3 * 36 + a = 180 or, 108 + a =180 or, a = 180 - 108 or, a = 72Related questions
