Answer:
The answer is J.
Step-by-step explanation:
Pythagorean Theorem: c² = a² + b²
The longest side appears to be 5 feet, which we can plug into the equation.
5² = a² + b²
Next, we can see that another side has already been shown, the 3 feet, so let's plug that in too.
5² = a² + 3²
25 = a² + 9
-9 -9
16 = a²
√16 = 4
We have now figured out the bottom of one triangle, but there is still another triangle that needs to be solved.
We can simply just add 4 + 4 together, which equals 8 feet, and is the width of the bottom of the tent.
