Question 176480: "A certain angle is 30 degrees less than 4 times it's compliment. Find the angle's supplement."
I need a step by step answer to the above word problem. Thank you in advance. Answer by Mathtut(3670) (Show Source):
You can put this solution on YOUR website! let a and b be our supplementary angles
:
b=4a-30..........eq 1
a+b=180..........eq 2
:
rewrite eq 2 to b=180-a and plug it into eq 1
:
180-a=4a-30
:
5a=210
: degrees
: degrees
