Question

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.

Answer 1

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.

Answer 2

Great explanation. Concise and direct. Guiding but not completely solving the answer for the student. I like.

Answer 3

180=x+3x+6x-2

Answer 4

Awe Matt, now Sea Princess will never learn to do these problems :-(
