Question

In a triangle ABC, angle B is 4 times angle A and C is12 degrees less than 5times angle A. Can someone help me find the size of the angles. I am confused.

Answer 1

you are given these facts:
B=4A
C=5A-12

you also know the sum of the angels of a triangle is 180, so:
A+B+C=180

you therefore have 3 equations with 3 unknowns and should be able to solve it.

Answer 2

I as wondering how they got 180 degrees..OK thanks, I'll go from there and see what i come up with..

Answer 3

good luck!

Answer 4

thanks..
