To secure a 500-meter radio tower against high winds, guy wires are attached to a ring on the tower. The ring is 5 meters from the top. The wires form a 75o angle with the ground. To the nearest hundredth meter find the length of the guy wire.
would this be tan75= 500-5
tan75=495/x
+130511 Your "set-up" is almost correct.....
But what does the tangent involve?? opposite and adjacent
And what are we looking for?? the hypoteneuse ....the length of the wire
What do we know?? an angle and the opposite side
And what function relates the opposite side and the hypoteneuse??
See if you can take it from here...
(I find it's helpful to draw a picture...also.....make sure you know your basic identities!!)
