The answer is the first option, which is: [tex] \frac{1}{2} [/tex]
The explanation for this problem is shown below:
1. You have the tangent ratio for the angle [tex] A [/tex] is:
[tex] Tan(A)=\frac{opposite}{adjacent} [/tex]
Where [tex] opposite=1 [/tex] and [tex] adjacent=2 [/tex]
2. When you substitute these values, you obtain:
[tex] Tan(A)=\frac{1}{2} [/tex]
Therefore, the answer is the option mentioned above.
