Answer:
d = 5
Step-by-step explanation:
Pythagorean Theorem
a^2 = b^2 = c^2
3^2 + 4^2 = 9 + 16 = 25
sqrt.25 = 5
D. 5 feet
You can imagine the ladder forming a right triangle with the wall. The two legs are 3 feet and 4 feet. Using the Pythagorean Theorem:
[tex]l=\sqrt{4^2+3^2}=\sqrt{16+9}=\sqrt{25}=5[/tex]
Hope this helps!
