Answer:
The value of cos(-1710°) is 0
Step-by-step explanation:
Given the angle 1710°
We have to find the cos of angle i.e cos(1710°)
As we know cos(-x)=cos x
\cos{-1710^{\circ}}=\cos{1710^{\circ}}=\cos({1710^{\circ}\times \frac{\pi}{180})}cos−1710
∘
=cos1710

=cos(1710

Answer:
option (A) ..... 0
Step-by-step explanation:
we have to find the value of (-1710°)
let (-1710°) be ( 1710°)
cos ( 360°×4+270°)
cos 270°
cos ( 180° - 90°)
cos 90°
1710°= cos 90°
-1710° = - cos 90°
cos 90°= o
