Question

The measure of the supplement of an angle is 60 less than three times the measure the complement of the angle. Find the measure of the angle

Answer 1

supplement + complement = 180 or 360?

Answer 2

suppl=180
compl=90

Answer 3

127.5?

Answer 4

angle = x, compliment to x = c, supplement to x = s
x+c = 90
x+s = 180
s = 3c - 60

solve for x using substitution

Answer 5

so:
x+c = 90 ==> x = 90 - c
so:
x+s = 180
[90 - c] + s = 180
s = 180 - 90 + c
s = 90 + c

and
s = 3c - 60
so:
3c - 60 = 90 + c
2c - 60 = 90
2c = 150
c = 75

so if c = 75
x + c = 90
x + 75 = 90
x = 15

so s = 175
c = 75
x = 15

cool, but did that all make sense dude?
like, do u understand all the working out ok?
