Question

Calculations show that an angle is $37{\frac{1}{2}}^{\circ }$. The size obtained by drawing and measurement is ${35}^o$. Find the error in percent.

Answer 1

Actual measurement of the angle $=37\frac{1}{2}$ degrees or $37.5$ degrees.

Wind measurement of the angle $=35$degrees.

Difference between both $=37.5-35=2.5$ degrees.

Error percent = $\frac{Differencebetweenboth}{actualmeasurementofangle}\times 100$

$=\frac{2.5\times 100}{37.5}$

$=6.66\%$

$\therefore$ Error percent $=6.66\%$
