Answer:
Step-by-step explanation:
Tan A = Sin A/Cos A
Cot A = Cos A / Sin A
Sin A*Cos A * tan A + Cos A * Sin A * Cot A

Rewrite in standard form to find the center (h,k) (h,k) and radius
Center: (5,7)
Radius: 9
The answer is the second choice, ie false
Answer:
39.62323
Step-by-step explanation:
You can use the Pythagorean Theorem to find the length of the hypotenuse of a right triangle if you know the length of the triangle's other two sides, called the legs. Put another way, if you know the lengths of a and b, you can find c.
c=a2+b2=392+72≈39.62323
