Answer:
the error is 7-6.33=0.67
the percentage of error is (0.67/7)×100≈9.5%
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.
