Question

If 3 tanA = 4 then sinA =​

Answer 1

Step-by-step explanation:

3tanA = 4

tanA = 4/3

tanA = opp/adj = 4/3

hyp² =s²+s²

h² = 16 +9

h² = 25

h = 5

sin A = opp / hyp

= 4/5

cos A = adj/hyp

= 3/5

∴sin A = 4/5

cos A = 3/5

Answer 2

Answer:

3 tan A= 4

tan A= 4/3

sinA/cosA = 4/3

sin A= 4/5
