Question

calculation show that an angle is 37 whole 1 upon 2 degree the size of them by the wind measurement is 35 degree find the error per cent

Answer 1

Error = (75/2 - 35)°
5/2°
Error % = (5/2°) / (75/2°) × 100%
20/3°

Answer 2

Solution :-

Actual measurement of the angle = 37 1/2 degrees or 37.5 degrees

Wind measurement of the angle = 35 degrees

Difference between both = 37.5 - 35

= 2.5 degrees

Error percent = (Difference between both angles*100)/Actual measurement of the angle

⇒ (2.5*100)/37.5

250/37.5

= 6.66 %

So, the error percent is 6.666 %
