- Homework Statement
- Find the length ##XY## by considering the given diagram
- Relevant Equations
- cosine rule, similarity, pythagoras theorem
i saw this question on the internet. The people responding were of the opinion that the length##xy=1##, but no working...first of all is the answer ##1## correct?
i am trying to find the steps to solution, i have managed to find an angle ##57.27^0## by cosine rule, i tend to think that i need to sort of find the angles then calculate the length. My other thinking is to use similarity. Am still trying to work on it. cheers
