Question:

If tanA - tanB - tanC = tanA tanB tanC, then find the value of A in terms of B and C.

Options:

A = 2B - C

A=\(\frac{B-C}{2}\)

A = B + C

A = 2C + B

Correct Answer:

A = B + C

Explanation:

Put B = 0 and satisfy the options.

Given → tanA - 0 - tanC = 0

tanA = tanC

So, take option C'

A = 0 + C

A = C satisfied.
