Question

if sinA=12/13 and cos A=5/13 find tanA​

Answer 1

Given :

• sinA=12/13

• cos A=5/13

To find :

• tan A

Formula used :

• tan A = sin A / cos A

Solution :

To find tan A , use the given formula :-

⟹ tan A = sin A / cos A

⟹ tan A = (12/13) / (5/13)

⟹ tan A = (12×13) / (5×13)

⟹ tan A = 12/ 5

Answer :

tan A = 12/ 5
