- 4/7 + 8/3
- = 12/21 + 56/21
- =

- = 3 5/21.
- = 68/21.
It’s is b why u covering your camera lol
(34/8 - 16/9) = 89/36
(89/36 - 14/9) = 11/12
ANSWER: 11/12
Answer:
Step-by-step explanation:
Sinθ = 
If, sinθ = -
and π < θ < 
Since, sinθ is negative, angle θ will be in IIIrd quadrant.
And the measure of angle θ will be (180° + 30°)
θ = 210°
It's necessary to remember that tangent and cotangent of angle θ in quadrant III are positive.
Therefore, cos(210°) = 
tan(210°) = 
csc(210°) = 
sec(210°) = 
cot(210°) = √3
Sorry I don't what the answer would be for A. But B would be (3,13)
