Question

if 4 tan A=3 find sinA? ​

Answer 1

Answer:

given

4 tan A = 3

tana=3 /4

we kown that tanA = p/b

p=3 , b=4 and h=?

According to Pythagoras theorem

h^2=p^2 + b^2

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

= 9 + 16

= 25

h = √25 = 5

h= 5

Now,

Sin A = p/h

Sin A = 3/ 5

This you answer

Hope this help

Answer 2

Answer:

sinA=3/5

Step-by-step explanation:

TanA=3/4

TanA=opp/adj

opp=3

and we know that 3,4,5 are Pythagoras triplet

sinA=opp/hyp

sinA=3/5
