Question

if sin A =3/5 find that tan A

Answer 1

it is very easy yrr

sin a= 3/5 p/h

using Pythagoras theorem

b square = h square - p square

b square = 5 square - 3 square

b square = 25-9

b square = 16

b=√16

b=4

tan a = p/b= 3/4 is answer

Answer 2

Hi friend...
sin A = 3/5 (which is opposite side /hypotenuse)

Then 3 is opposite side and 5 is the hypotenuse.

Then let the adjacent side be x.

By Pythagoras theorem,
5^2 = x^2 + 3^2
25=x^2+9 (by transposing)
25-9= x^2
16 = x^2
(root of 16) 4=x.

tan A= opposite side /adjacent side
= 3/4.

Hope it helps
