A ladder leans against a vertical wall of height 12m.if the foot of the ladder is 5m away from the wall,calculate the length of the ladder.

Answer 1

the ladder, wall, and ground form a Pythagorean triple (like 3-4-5)

this one is 5-12-13

Answer 2

Pls calculate it for me

Answer 3

No answer

Answer 4

This resembles the right angle triangle cuz the ladder leaning the wall the foot away from the wall and the length of the ladder represents the right angle triangle.
Let a be the height of the wall (12m),b , the foot of the ladder away from the wall(5m) and c the length of the ladder which is unknown.
.·.a2+ b2=c2
(12m)2+(5m)2=c2
144m+25m =c2
169=c2
Square root of 169& c
13=c
.·.the length of the ladder is 13m
