OpenStudy (anonymous):

You're saying x=120 degrees?

OpenStudy (amistre64):

OpenStudy (amistre64):

or do you mean the value of x part of pointA'' from the movement?

OpenStudy (anonymous):

Is seems like that's too easy...like It's a trap :)

OpenStudy (amistre64):

the only x i see in teh picture is the angle. and theyve already defined it.

OpenStudy (anonymous):
