Question

Find the value of: tan10°.tan15°.tan60°.tan75°.tan80°

Answer 1

Answer:

$\tan(10) . \tan(15) . \tan(60) . \tan(75) . \tan(80) = \sqrt{3}$

Answer 2

Answer:

√3

Step-by-step explanation:

First make couple of values which add to 90°

So

(Tan10°×tan90°)(tan75°×tan15°)(tan60°)

Now, as when multiplied ,first and second bracket will nullify

So,

(1)(1)(tan60°)

Tan60°=√3

Thus the answer is √3
