Answer: Sin A = 3/5
Cos A = 4/5
Tan A = 3/4
Explanation:
Looking at the right angle triangle ABC, taking angle A as the reference angle,
AC represents the hypotenuse
BC represents the opposite side
AB represents the adjacent side.
1) Sin θ = opposite side/hypotenuse.
Sin A = BC/AC
Sin A = 3/5
2)Cos θ = adjacent side/hypotenuse
Cos A = AB/AC
Cos A = 4/5
3)Tan θ = opposite side/adjacent side
Tan A = BC/AB
Tan A = 3/4
