Answer 2

Answer:

tan 45°=1

B is correct.

Step-by-step explanation:

In given right angle triangle.

Two angles are equal.

Using trignometry identity.

For right triangle

$\tan\theta=\dfrac{P}{B}$

For given triangle P=B=1

Ф=45°

Substitute into formula

$\tan45^\circ=\dfrac{1}{1}$

$\tan45^\circ=1$

Hence, The value of tan 45°=1
