Angle PQR is formed by segments PQ and QR on the following coordinate grid: Angle PQR is rotated 90 degrees counterclockwise about the origin to form angle P'Q'R'. Which statement shows the measure of angle P'Q'R'?

m∠P'Q'R' = 90 degrees
m∠P'Q'R' = 180 degrees
m∠P'Q'R' = m∠PQR
m∠P'Q'R' = 2 ⋅ m∠PQR

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.
