Relativity length contraction problem

[Fizex]

Homework Statement

A meter stick moves with speed .8c relative to frame S. What is the length observed by a person in frame S if the stick is 60 degrees to v, as measured in S?

Homework Equations

L=observed length
l=proper length
y=1/sqrt(1-B^2)
L=l/y
