Answer:
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
