Calculations show that an angle is 3712∘. The size obtained by drawing and measurement is 35o. Find the error in percent.
Actual measurement of the angle =3712 degrees or 37.5 degrees.
Wind measurement of the angle =35degrees.
Difference between both =37.5−35=2.5 degrees.
Error percent = Differencebetweenbothactualmeasurementofangle×100
=2.5×10037.5
=6.66%
∴ Error percent =6.66%
