20

Step-by-step explanation:

We can use the Pythagorean Theorem to find this: a² + b² = c²

Following that, c² is always the hypotenuse. All we have to do is plug in the variables and solve:

Step 1: Replace variables

12²+16² = c²

Step 2: Solve

144+256 = c²

c² = 400

√400 = √c²

c = 20

And you get x = 20 as your final answer!

what is the information provided?

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":

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.
