Question 1164806
It appears there are a few typos in your expression. Based on standard trigonometric shorthand, I will interpret your equation as:

If "csn" was meant to be **** and "tan2" meant ****, we can solve it as follows:

### 1. Simplify the Trigonometric Terms

First, let's rewrite everything in terms of  and  to see if the expression simplifies.

* 
* 

Now, substitute these back into the equation:


### 2. Find a Common Denominator

Since , the equation becomes:


### 3. Solve for 

This is a transcendental equation, which usually requires numerical methods or a graphing calculator to solve precisely. However, we can test small values since  is close to zero.

If we let :

* If , then .
* Since the result is slightly negative (),  must be a small negative angle.

Using the small-angle approximation where  and :


Using the quadratic formula :


### 4. Convert to Degrees

Checking this in the original equation:
 (Very close to ).

**Solution:**


*(Note: If the "tan2" in your prompt meant  or if "csn" meant something else, the solution would change.)*

**Would you like me to re-calculate this using a different interpretation of the symbols?**
