Question 497510: An angle is 20 degrees more than four time its complement, how do I figure this out? I know what a complement is, I just don't know how to figure this problem out since I wasn't given an original degree.
Also:
Find the supplement of angle A if m(A = 3x + 50.
How do I figure this out as well?
I am not looking for the answer, unless you are going to provide me with detailed steps with it. I am looking for an explanation on how to figure it out this way I can figure out other similar problems! Please don't just hand me an answer I need steps and thorough explanations that I can understand! Thank you!

You can put this solution on YOUR website!
let angle be x
complement = (90-x)
4 times = 4 (90-x)
20 more
x= 4(90-x)+20
x=360-4x+20
5x=380
x=76
m(A) = 3x+50
supplement = 180-(3x+50)
=180-3x-50
=130-3x
...
CHECK
add them up you get 180 deg
