If sin A = 8/17 find the value of cos A and tan A – InterviewSolution

1.

If sin A = 8/17 find the value of cos A and tan A

Answer»

COS A =

tan A =

Step-by-step explanation:

Sin²A + Cos²A = 1

Cos²A = 1- Sin²A

= 1-(8/17)²

= 1-(64/289)

= (289-64)/289

= 225/289

= ±15/17

SinA/CosA = tanA

tanA= (8/17)/(15/17)

= ±8/15
