The value of (1 + tan 10o)(1 + tan35o) is:
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 2
Concept used:
If A + B = 45°, then
(1 + tan A)(1 + tan B) = 2
Calculations:
According to the concept, we have
⇒ A + B = 10 + 35 = 45
Hence, (1 + tan 10)(1 + tan 35) = 2
