Find `x` from the following equation: `xcot(90^0+theta)+tan(90^0+theta)sintheta+cosec(90^0+theta)=0`

Explanation

To solve the equation \( x \cot(90^\circ + \theta) + \tan(90^\circ + \theta) \sin \theta + \csc(90^\circ + \theta) = 0 \), we can follow these steps:

### Step 1: Rewrite the trigonometric functions
Using the trigonometric identities:
- \( \cot(90^\circ + \theta) = -\tan \theta \)
- \( \tan(90^\circ + \theta) = -\cot \theta \)
- \( \csc(90^\circ + \theta) = \sec \theta \)
