Given that cot A = 16/63 and that angle A is in Quadrant I, find the exact value of cscA in simplest radical form using a rational denominator.

Answer:
Below in bold.
Step-by-step explanation:
cot = adjacent side / opposite side = 16/63
So the hypotenuse = √(16^2 + 63^2)
= √4225
= 65.
So csc A = hypotenuse /opposite side
= 65/63
