Remember that the total of the angles always equals 180 degrees4x + 2 + 8 + 6x + 30 = 180Now solve4x + 2 - 2 + 8 + 6x + 30 = 180 - 24x + 8 - 8 + 6x + 30 = 178 - 84x + 6x + 30 - 30 = 170 - 304x + 6x = 14010x = 14010x ÷ 10 = 140 ÷ 10x = 14 Now that we know what x is we can fill in the blanks4(14) + 258 + 258Angle O is 58 degrees 8 + 6(14)8 + 8492Angle R is 92 degrees To check we can add them all up30 + 58 + 92 = 180 x = 14
