2. what is the length of the unknown side?

side 1 = x
side 2 = 16
side 3 = 12
a. 28 units
b. 14 units
c. 20 units
d. 200 units

To determine the length of the unknown side, you need to use the Pythagorean theorem which states that for a right triangle, the sum of the squares of the two legs is equal to the square of the hypotenuse.

In this case, let's assume that side 1 (x) is the missing side and apply the theorem:

x^2 + 12^2 = 16^2

Simplifying the equation results in:

x^2 + 144 = 256

Subtracting 144 from both sides gives:

x^2 = 112

Taking the square root of both sides, we get:

x ≈ 10.6

Therefore, the length of the unknown side (side 1) is approximately 10.6 units.
