1. The problem statement, all variables and given/known data

I attached a picture below...

2. Relevant equations

sin^2(theta)+cos^2(theta)=1

a^2+b^2=c^2

Vector properties

Trig identities

3. The attempt at a solution

I am familiar with trig identities and vector properties, but I can't get anywhere with this. I tried using the 697N weight as the y-component vector for either side, but that didn't work.
