Answer 2

Step-by-step explanation:

Given: $tan\:5 B = 1$

To find: The value of B is equal to

(A) 9°

(B) 90°

(C) 45°

(D) 30°

Solution:

We know that

$tan \: 45° = 1$

Replace 1 by tan45° in RHS

$tan \: 5B = tan \: 45°$

cancel tan from both sides

$5B = 45°$

$B = \frac{45°}{5}$

$B = 9°$

Final answer:

$\bf B = 9°$

Option A is correct.
