Find the exact value of tan 195 degrees
melamori03 [73]

Answer:

tan(195\°)=tan(15\°)=0.267949192431123...

Step-by-step explanation:

We know that

tan(195\°)=tan(15\°), because 195\° - 180\° = 15\°.

Now, angle 15° or 195° is not an important angle which can be solve by a given table like 30°, 45° or 60°. This means we have to use the calculator to find the more exact value, which is

tan(195\°)=tan(15\°)=0.267949192431123...
