Two students are doing a report on the intensity of light passing through a filter. after some research, they each find a different formula for the situation. in each formula, i is the intensity of light passing through the filter, i₀ is the initial light shining on the filter, θ is the angle between the axes of polarization. theo’s formula: i = i₀ cos² θ sany’s formula: i = i₀ - i₀ / csc² θ prove that the two formulas are equivalent.

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":

we must add 15 to both sides of the equation:

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

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