Question

Given ∠A = 75°, ∠B = 30°, then tan (A-B) = ………

A) √3

B) 1/√3

C) 1

D) 1/√2

Answer 1

Correct option is: C) 1

<A = \(75^\circ\) & B = \(30^\circ\)

\(\therefore\) A -B = \(75^\circ\) -  \(30^\circ\) = \(45^\circ\)

\(\therefore\) tan (A-B) = tan (\(45^\circ\)) = 1

Answer 2

Correct option is: C) 1
