Add all the angles together. They have to equal 180. Write and solve the equation that says that.

OpenStudy (anonymous):

ok, i actually did that and i got 10. which seems really wrong

@Mertsj

OpenStudy (anonymous):

OpenStudy (mertsj):

What is equal to 10?

OpenStudy (anonymous):

the added up angles

OpenStudy (anonymous):

OpenStudy (mertsj):

Did you write: \[4x+7+11x-9+32=180\]

OpenStudy (anonymous):

yup. i got 10

OpenStudy (mertsj):

So x=10

OpenStudy (anonymous):
