To find the length of the missing side, we need to know what type of shape or object we are dealing with (e.g., a triangle, rectangle, etc.) and what information we have about the sides.
Assuming you are asking about a right triangle and you have two sides measuring 8 and 16, you can use the Pythagorean theorem. The theorem states:
\[ a^2 + b^2 = c^2 \]
where \(c\) is the hypotenuse and \(a\) and \(b\) are the other two sides.
Let's assume the two sides you have (8 and 16) are the lengths of the legs (not the hypotenuse).
- If the sides 8 and 16 are the legs: \[ a = 8, \quad b = 16 \] \[ c^2 = 8^2 + 16^2 = 64 + 256 = 320 \] \[ c = \sqrt{320} \approx 17.89 \]
Rounded to the nearest tenth, the length of the hypotenuse \(c\) is 17.9.
- If one side is the hypotenuse (let's say 16 is the hypotenuse) and 8 is a leg, then: \[ 16^2 = 8^2 + b^2 \] \[ 256 = 64 + b^2 \] \[ b^2 = 256 - 64 = 192 \] \[ b = \sqrt{192} \approx 13.86 \]
Rounded to the nearest tenth, the length of the missing leg \(b\) is 13.9.
Please clarify the context if this is not what you meant!
