Find the exact value of tan θ.

Mathematics
1 answer:
FrozenT [24]3 years ago
5 0

Answer:

The answer is C.

Step-by-step explanation:

Recall SohCahToa, where tan(\theta)=opp/adj.

In the triangle, the opposite (to angle theta) is 6, while the adjacent is 2\sqrt{5}.

Put this into the equation:

tan(\theta)=\frac{6}{2\sqrt5}

Now, simplify: (multiply both top and bottom by \sqrt5

\frac{6}{2\sqrt{5} } \cdot\frac{\sqrt{5} }{\sqrt{5}} =\frac{6\sqrt{5}}{2(5)} =\frac{6\sqrt{5}}{10}=\frac{3\sqrt{5} }{5}

The answer is C.
