(3) 240
(4) 520

Open in App
Solution

Using formula 180=π radian
25=π180×25 radian
=5π36 radian
25=5π36 radian

Using formula 1=60
4730=473060 degree
=4712 degree
=952 degree
Using formula 180=π radian
952 degree =952×π180 radian
=19π72 radian
4730=19π72 radian

Using formula 180=π radian
240=240×π180×25 radian
=4π3 radian
240=4π3 radian

Using formula 180=π radian
520=520×π180 radian
=26π9 radian
520=26π9 radian
