the drawing is the vector with the angle does this make sense to you?

now with the mag being at 6feet and the angle that forms 25 degree angle what do we know about this?

hint take the vector as drawn and make triangle.

okay what is unclear to you? explain plz

So just to be clear, you drew the vector with the angle which can make an isosceles triangle. So now what?

if you read the problem it states there is a vector that has a 25 degree angle and maga of 6 feet. So, I took the what the problem and drew it out as to what the problem is asking for. The drawing is not to scare and could be a little off, but the point was to show you what it was saying

Oh o.k. Now I fully understand. So now, to solve

the reason for me having you form a triangle is to get you not so scared of the vector is all
godorovg
Best Response

because vectors are scary things if you don't know them

so we have angle 25 degrees and 6ft and the answers are 2. something so if this is trig what should be done now I would think we should considers sin or cos of 6times what you say?
godorovg

so in other words 6sin(25)=
