[C]
Step-by-step explanation:
The ray in the terminal position, after the rotation is call the "terminal side of the angle."
Note that quadrant of the unit circle of any given angle the radians would be in:
Quad I → 0 < θ < pi/2
Quad II → pi/2 < θ < pi
Quad III → pi < θ < 3pi/2
Quad IV → 3pi/2 < θ < 2pi
Hence, Answer is [C] pi/2 radians

Answer:
Height of the building = 50.8 ft
Step-by-step explanation:
A person and a building are casting the shadows at the same time of the day.
Triangles formed by the person and his shadow and the building and its shadow will be similar.
Therefore, corresponding sides of the similar triangles will be proportional.
x =
x = 50.75
x ≈ 50.8 ft
