Answer:
Option A
Step-by-step explanation:
It's given that cosθ = 
Since, cosθ = 
=
= 
By applying Pythagoras theorem in the right triangle,
(Hypotenuse)² = (Opposite side)² + (Adjacent side)²
(√5)² = (Opposite side)² + (2)²
5 = (Opposite side)² + 4
Opposite side = √(5 - 4)
= 1
Since, sinθ = 
= 
Since, sine is positive in IInd quadrant,
sinθ =
Therefore, option A will be the answer.
Answer:
in 9 hour 10 minutes the water level decreased = 5/12
