Hi, can someone help me with a couple of pre-calculus questions?

OpenStudy (anonymous):

Probably.

OpenStudy (anonymous):

Do you have any other questions?

OpenStudy (anonymous):

sweet! okay thanks! yes hold on

A guy wire to a telephone makes a 67 degree angle with the ground. At a point of 20 ft farther out from the guy wire, the angle of elevation of the top of the pole is 35 degrees. How long is the guy wire?

OpenStudy (anonymous):

Hmm, this is what I imagine that looks like. |dw:1351383832263:dw| Does that seem reasonable to you for this situation?

OpenStudy (anonymous):

wow, haha i guess! yes. so whats next?

OpenStudy (anonymous):

|dw:1351384077236:dw| How big is angle Θ?

OpenStudy (anonymous):

correct. !!

OpenStudy (anonymous):

Also, do you know the Law of Sines and Law of Cosines?

OpenStudy (anonymous):

oh wait, \[\theta\] isn't shown and yes i do

OpenStudy (anonymous):

Solve for Θ.

OpenStudy (anonymous):

so \[\sin x\] divided by 20 ?

OpenStudy (anonymous):

is theta 113?

OpenStudy (anonymous):

Yes, Θ=113. |dw:1351384565964:dw| How about this angle? α=?
