Question

If tan A=3 by 4 then sin A is??my answer is 3 by 5 is this right??

Answer 1

Answer:

yes you are right. we know the adjacent side is 3 and hypptenuse is 5 (pythagoreas theorem). sina is adj/hypo

so the answer is indeed 3/5 ...well done :)

Answer 2

Answer:

yes it is right...

well done

Explanation :

tan A =3/5

perpendicular =3

base=4

by using Pythagoras theorem

hypotenuse=5

→so sinA =perpendicular/hypotenuse

= 3/5
