A firefighter places a 13 ft. ladder against the wall of a burning building. IF the bottom of the ladder is 5 ft from the base of the building, how far up the building will the ladder reach?​

Respuesta :

Answer:

12 ft

Explanation:

we will use pythagoras theorem

a² + b² = c²

according to the given data we'll assume that

a = 5

c = 13

5²+b²=13²

25+b²=169

b²=169-25

b²=144

b=√144

b=12

Answer:

It would be 12ft because if you do the certain math, concluding that you'll be using the 5 and the 13 it will lead to 12
