A simple geo problem
Hey, I've never been good at math so would you mind explaining to me a few problems? =]
1.The measure of the supplement of an angle is 60 less than 3 times the measure of the complement of the angle. Find the measure of the angle.
2.Find angle T if angle T is 20 more than 4 times its supplement
Thanks.

The measure of the supplement of an angle is 60 less than 3 times the measure of the complement of the angle. Find the measure of the angle.
if an angle measures x, then it's supplement is 180x
similarly it's complement would be 90x
then saying
"the supplement is 60 less than 3 times the complement"
180x=3(90x)60
180x=2703x60
180x=2103x
x=303x
2x=30
x=15

Find angle T if angle T is 20 more than 4 times its supplement
if T measures t degrees, then it's supplement would be 180t
then
"t is 20 more than 4 times its supplement"
t+20 =4(180x)
...similar algebra to solve for x
