Question 23111: The section we are working on has to do with augmented matrices, and here's the question:
"In triangle ABC, the measure of angle A is twice the measure of angle B. The measure of angle C exceeds four times the measure of angle B by 12 degrees. Find the measure of each angle."
I've tried this problem several times and just can't find a reasonable answer. Please help. Answer by rapaljer(4671) (Show Source):
You can put this solution on YOUR website! Let x = angle B since it is at the end of the first sentence and because angle A is described in terms of angle B. Therefore, let x = angle B
2x = angle A
4x +12 = angle C
The equation is that the sum of the three angles is 180 degrees.
x+ 2x + 4x + 12 = 180
7x + 12 = 180
7x = 168
degrees = Angle B degrees = Angle A degrees = Angle C
