Question

19. If cos A = 4/5, then tan A = ?​

Answer 1

Step-by-step explanation:

However, cos(a)<0 .

So, cos(a)=−45

Now, let’s evaluate the value of tan(a) :

⇒tan(a)=(35)(−45)

=−34

Answer 2

Answer:

tanA=3/4

Step-by-step explanation:

cos A=4/5

sin A = 3/5

Tan A = sin A / cos A

Tan A = 3/4
