Question

An angle whose supplement is 3 times the measure of it supplement

Answer 1

you dont have a complete sentence

Answer 2

\[180-\theta=3(180-\theta) \implies \theta=180 degrees\]

Answer 3

the english is screwy

Answer 4

i did what I understood ;)

Answer 5

well that is how the question is wrote out for me?

Answer 6

you got an absurd conclusion

Answer 7

no , write it again and double check

Answer 8

Find the measure of an angle whose supplement is 3 times the angle.

Answer 9

Thats the question

Answer 10

oops, the last word is complement, sorry its late

Answer 11

x + y = 180, y = 3x

Answer 12

\[180-\theta=3(90-\theta) \implies 2\theta=90 \implies \theta=45\]

Answer 13

3x + x = 180
x = 45

Answer 14

y = 135

Answer 15

\[if \ \theta>90\ then\ 180-\theta=3(\theta-90) \implies \theta=112.5\ else\ \theta=45\]

Answer 16

I'm not sure what ask but i think 2 way can solve
frist:
180-x=3(90-x) or: 180=3(90-x)
180-x=270-3x 180=270-3x
-x+3x=270-180 -270+180=-3x
2x = 90 -90 = -3x
x= 90 -90/-3=x
x=45 30 = x

Answer 17

@Nancy Lam: you are assuming that x<90. What if x>90?
