Question

if sin A= 3/4 calculate cos A and tan A​

Answer 1

Step-by-step explanation:

CosA=adjacent/hypotenuse

tanA= opposite /adjacent

Answer 2

Answer:

cos A= √7/4

tan A= 3/√7

Step-by-step explanation:

sin A= opposite side /hypotenuse

therefore opposite side =3 and hypotenuse =4

so we can calculate base by Pythagoras theorem, i.e base = √7

cos A= base/ hypotenuse= √7/4

tan A= opposite side /base= 3/√7

hope it will help you.
