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 6x degrees. What is the value of x? Express your answer as a decimal to the nearest tenth.
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 6x degrees. What is the value of x? Express your answer as a decimal to the nearest tenth.
A = x B = 2x C = 6x
A + B + C = 180o
x + 2x + 6x = 180o
9x = 180o —>> x = 20.0o
