Answer Please.​

sinA = 4/5

cosA = 3/5

tanA = 4/3

Step-by-step explanation:

We calculate the calue of sinA by

dividing the opposite side with hypotenuse :

sinA = 12/15 and if we simplify fraction it will be 4/5

for cosA we divide adjacent side by hypotenuse :

9/15 simplified = 3/5

and for tanA we divide opposite side by adjacent side :

12/9 simplified = 4/3

because they could drop even lower..
