step-by-step explanation:

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.

the answer is a) y= 2 csc [0.5 (x+pi/2)]-1
