What is the angle between the adjacent and hypotenuse of the above right-angled triangle?
A) 36.87 degrees
B) 38.66 degrees
C) 53.13 degrees

The angle between the adjacent and hypotenuse is the cosine inverse of the adjacent/hypotenuse. So, we have cos θ = adjacent/hypotenuse. Plugging in the values, we get cos θ = 4/6, which simplifies to cos θ = 0.66667. Taking the inverse cosine, we get θ = 36.87 degrees, which is option A.
