Hello,
Center is (2,-11) and radius is 8
- 6/7
hope that helps if you divide it by 2 you you get your answer
tan (π/6) + sin (5π/3) . cos (- 3π/4)
= tan 30° + sin 300° . cos (- 135°)
= tan 30° + sin (360° - 60°) . cos 135°
= tan 30° + (- sin 60°) . cos (180° - 45°)
= tan 30° + (- sin 60°) . (- cos 45°)
= tan 30° + sin 60° . cos 45°
= (1/3)√3 + (1/2)√3 . (1/2)√2
= (1/3)√3 + (1/4)√6
= (4/12)√3 + (3/12)√6
= (4√3 + 3√6)/12
