Answer with explanation:
Out of six Trigonometric Ratios,that is ,sinθ,cosθ,tanθ,Cosecθ,tanθ, cotθ ,all are used for a right triangle.
For any right triangle
cot θ

They are similar. If two of the corresponding angles are the same, the third one is corresponding. If a triangle angles are, 60, 60, 60, that adds up to 180... but if a triangle's angles are ,60 ,60, 50, that is impossible. All angle measures must add up to 180*.
Answer:
Sin A= − 12/37
Step-by-step explanation:
tan A = − 12/35
Reason for minus sign is because of it's in the fourth quadrant.
12 = opposite
35 = adjacent
? = Hypotenuse
12² + 35² = hypotenuse ²
1369 = hypotenuse ²
hypotenuse = √1369
hypotenuse= 37
Sin = -12/37
Reason for minus sign is because of it's in the fourth quadrant.
Answer: 
Step-by-step explanation:
Suppose the missing polynomial be f(x)
So, we can write
