Vectors: Tension
a neon sign is held out from the side of his building by a horizontal aluminium ole.A wire, fastened to the building at an angle of 55(degrees) to the vertical. supports the entire weight of the sign. if the sign has a weight of 630 N under gravity, find the tension in the wire and the compression in the aluminim pole.

i did the diagram how the tension and the compression are related to ech other...i dont know how to do the question...any advices will help me to begin..thank you

$T\sin(35) = 630$

solve for $T$

compression force = $T\cos(35)$
