Consider the absolute value, because we only worry about the quadrant later.


Thus, we know that the hypotenuse has a length of 4 units, and the side opposite the angle, A is √3, because this is the nature of the sine function in relation to its triangular component.
The missing side can be found using Pythagoras' Theorem:
4² - (√3)² = x²
16 - 3 = x²
13 = x²
x = √13

Since angle A is in the third quadrant, the tangent function will produce a positive angle.

Answer:
-34
Step-by-step explanation:
22+n=-12
n=-12-22
n=-34
When you bring a positive constant to the other side of the equal sign it goes negative and vise versa. Then you combine like terms.
