It can't be solved. we don't know anything about the triangle thus formed..

OpenStudy (anonymous):

But it can since there is multiple choices?

OpenStudy (anonymous):

hey use external angle theorem

OpenStudy (anonymous):

Still it can't be solved... tried applying it.

OpenStudy (anonymous):

It can. Do it like this: z-13 = 180-z + 180-(z+10) This yields the answer: z = 121

OpenStudy (anonymous):

Guess I am too sleepy.. :/

OpenStudy (anonymous):

Wait so z would be what?

OpenStudy (anonymous):

Understandable after a hardworking day. If it's too early for bed than I would recommend a power nap :) z would be 121 degrees.
