**1.**Find the tension in each cord if the weight of the suspended object is w. (I am only asking about part a)

**2.**Net force on an object in equilibrium = 0

**3. part a)**I know this isn't the typical solution for this type of problem but I don't understand why it's not working.

I used the sine law: (Ta)/(sin45) = (Tb)/(sin30)

Then cosine law: w

^{2}= (Ta)

^{2}+ (Tb)

^{2}- 2(Ta)(Tb)cos75

I combined the equations to solve for Tb in terms of w. The answer I get doesn't match the given answer, so I'm wondering if there is something wrong with how I set up the problem.
