Answer:

C. 14 feet

Step-by-step explanation:

THIS IS TO FIGURE OUT THE TRIANGLE

You have to do the Pythagorean Theorem, which is a² + b² = c²

Since h is the entire piece of wood including the additional 2 feet, I will use m as variable for triangle

Fill in for variables: 5² + m² = 13²

Simplify: 25 + m² = 169

Subtract 25 from both sides: m² = 144

Square root both sides to get m alone: m = 12

Now, you have to add the additional 2 feet above the triangle: 12 + 2 = 14

Therefore, h=14

Answer:

12

Step-by-step explanation:

The only answer that makes sense. If you use pythagorean theorem which is a^2+b^2=c^2, and c is the hypotenuse, which is the slanting side, you do this

12^2+5^2=13^2?

144+25=169

169=169

it checks!
