In triangle ABC, the measure of angle A is x degrees, the measure of angle B is 2x degrees and the measure of angle C is 8x degrees. What is the value of x? Express your answer as a decimal to the nearest tenth.
+36916 In any triangle, all of the angles sum to 180o
soooo....
A + B + C = 180
x + 2x +8x = 180
11x = 180
x = 180/11 =..........
