Complement and Supplement of an angle
Find the measure of angle A if 5 times the complement of angle A is 150 greater than the supplement of angle A.
I have this
Let s be supplement and c be complement.
180-A = s
I plugged the above in.
Then plugged in my definition for c.
5(90-A) - 150 = 180 - A
450-5A + A=180 + 150
Huh. That's strange I got it right this time.
ANyway, there must be an easier way to do this. I think I used some things the book hadn't taught yet.
