Answer:
The decimal point should be placed after the 0 in 45780.
Step-by-step explanation:
In the equation given, the Distributive Property is being demonstrated.
Both sides aren't equal because 1-sin^2x = cos^2x and cos^2x / 1+cosx can never equal cosx
Both sides are symmetrical by the length and the shape
Cot = Cos/Sin
Cos = 12/13
Sin = 5/13
Therefore, 12/3 divided by 5/13 equals 12/5
Answer is 1.
