Question

If tan A=4/3 then sin A=___​

Answer 1

Answer:

tanA=4/3= opp/adj

by using pythogoras theory

AC2 = AB2+BC2

= 9+16

= 25

therefore, AC= 5

and sinA= opp/hyp

=4/5

Answer 2

Step-by-step explanation:

tanA=4/3

perpendicular =4x

base=3x

hypothenues =?

applying Pythagoras theorem

(p) ^2+(b)^2 =(h)^2

(4x)^2+(3x)^2 =(h)^2

16x^2+9x^2=h^2

25x^2=(h)^2

taking root both side

5x=h

sinA=p/h

=4x/5x

=4/5 ans........
