Help please, and help me answer the other ones Ive posted if you can, don’t comments just for points please, I really need help and a explanation m.

Answer 1

Explanation:

the Pythagorean Theorem.

A^2 + B^2 = C^2

In this case, A = 13 and B = 5. C = length of ladder.

13^2 + 5 ^2 = c^2

169 + 25 = 194

194 = c^2

square root both sides and you get:

c = 13.9
