THis isn't exactly a question however, its a method my teacher talked to me about and I don't quite understand.
This is a way of getting greater accuracy, and attaining the higher grades.
The question states, tan(angle) = 3/4
So instead of using tan^-1 (3/4) to get the angle with many digits, round it off and losing accuracy, she said:
Drawing the triangle out results in:

Using pythag you can work out the other side.
Now you have:
sin(angle) = 3/5
cos(angle) = 4/5
I have worked out the statement:
2Tsin(angle) = 3mg
However, how do I apply what was attained from the triangle to this question?
Thanks.
