Answer:
Step-by-step explanation:
Triangle ABC is a right angle triangle.
From the given right angle triangle,
AB represents the hypotenuse of the right angle triangle.
With ∠A as the reference angle,
AC represents the adjacent side of the right angle triangle.
BC represents the opposite side of the right angle triangle.
To determine AC, we would apply the cosine trigonometric ratio
Cos θ = opposite side/hypotenuse. Therefore,
Cos 56 = AC/6
AC = 6Cos 56 = 6 × 0.5592
AC = 3.3552
Rounding to the nearest tenth, it becomes
3.4
