Answer 1

Answer:

13

Step-by-step explanation:

In this concept, it forms a right triangle because it is 5 feet high, the base is 12 feet horizontally, and you need to find the hypotenuse (the longest side of the triangle/the slanted side). In this case, you can use the Pythagorean Theorem, which is $a^{2}+b^{2}=c^{2}$, where a and b are the lengths of the triangle, and c is the hypotenuse.

-We know a and b already, which are 5 and 12. So substitute a and b in the equation:  $5^{2}+12^{2}=c^{2}$

-Then, simplify to get:  $25+144=c^{2}$

-Add the 25 and 144 to then get:  $169=c^{2}$

-Find the square root of both sides to only get c left (the hypotenuse): $\sqrt{169}=\sqrt{c^{2}}$

-Then you’ll get: $\sqrt{169}=c$, which simplifies to $13=c$

ANSWER: 13

Hope this helps and answers your question! :)

Answer 2

Answer:

5^2+12^2= c^2

25+144=c^2

169=c^2

find the square root of 169

the length is = 13 ft
