Road

The angle of a straight road is approximately 12 degrees. Determine the percentage of this road.

Result

p =  21.3 %

Solution:

tan(12)=a/b p=100 a/b p=100 tan(12)21.2557=21.3%\tan(12^\circ ) = a/b \ \\ p = 100 \ a/b \ \\ p = 100 \cdot \ \tan( 12^\circ ) \doteq 21.2557 = 21.3 \%



Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
