c = 3(a+b)-4
I am unable to solve for the three angles. Your help is appreaciated.
Thank you. Found 2 solutions by armidano, josmiceli:Answer by armidano(1) (Show Source):
You can put this solution on YOUR website! You have 3 unknowns
That means you need 3 equations, or you can't solve.
The one you're missing is:
a + b + c = 180 That's true of all triangles
[1]
[2]
[3]
expand [2]
subtract c from both sides
[4]
add 4 to both sides
multiply both sides of [3] by 3
subtract one from the other
substitute in [4]
[5]
[1]
muiltiply both sides by 3
add to [5]
[3]
check

OK
so,
a = 20 degrees
b = 26 degrees
c = 134 degrees
