Question

sec 1755° find the value of trigonometric​

Answer 1

Answer:

0=thetha

Step-by-step explanation:

cos 1755

= cos( 3* 360+675)

= cos 675°

= cos (360°+315°)

= cos 315°

= cos (360°- 45°)

= cos 45°

= 1/2

Answer 2

Answer:

Step-by-step explanation:

1755° = (360° * 4) + 315°

we can conclude: sec(1755°) = sec(315°)

sec(315°) = sec(360°-45°) = sec(-45°) = sec(45°) = √2
