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

the answer is 510

step-by-step explanation:

15 • 13 = 195

15 • 12 = 180

15 • 5 = 75

12 • 5 = 60

195 + 180 = 375

375 + 75 = 450

450 + 60 = 510
