That's not what I get. I get (15/2)(√3-1)
How did you get your answer (which is not exact, by the way)?
A support wire to the top of a newly planted tree is 15 m long. It forms an angle of 30 degrees to the ground. On the same side of the tree, a second wire is also attached to the top of the tree, but it makes an angle of 45 degrees to the ground. Determine an exact expression for the distance between the points where the two support wires are attached to the ground.
I tried this question and got 2.0 metres. Is this correct?

How did you get your answer please tell me
A better question might be how did you get yours? Did you draw a diagram? since sin(30) = 1/2, the pole is 15/2 meters tall.
A 45-45-90 triangle has equal legs, so base of the 2nd wire is 15/2 meters from the pole.
I'll leave the rest to you. The Pythagorean Theorem should help.

Same question as above. Steve got the answer correct, but I'm having trouble laying it out with the diagram. Any one willing to walk this through with me step by step in a tutoring way? I want to learn not just have an answer. Thanks
