Question

Find the value of, Cos (-1710°)​

Answer 1

The answer is

cos(-1710°)

=cos(1710°)

=cos(1710× π )

180

=cos( 19π )

2

=cos(9½π)

=cos(10π - π )

2

=cos(- π )

2

= cos ( -180 )

2

=cos (- 90°)

= cos 90°

= 0

Hence the answer is 0

hope this helps u ☺️✌

Answer 2

Answer:

cos(-1710°)=0

Step-by-step explanation:

Adding 10*180° to -1710° gives 90°, so cos(-1710°)=cos(90°)=0
