Can anyone break down this math problem? In a triangle ABC, angle B is 3 times angle A and angle C is 2degrees less than 6 times angle A.
Ok, So you know that the sum of all the angles need to be 180. Here are some facts you know about the various angles, as algebraic expressions: B=3A (equation 1) C=6A-2 (equation 2) And you know A+B+C=180 Sub in what you know about B and C into the above equation. You'll end up with 10A = 182. You can then solve for A, and use your answer for A to solve for B and C using equations 1 and 2. Let me know if this makes sense or if you need more help.
Great explanation. Concise and direct. Guiding but not completely solving the answer for the student. I like.
Awe Matt, now Sea Princess will never learn to do these problems :-(
