If the ladder is 10 m long and 5 m from the base of the building, how high up the building will the ladder reach? (1 point) Responses 10^2−−−√+5^2=c^2 ; c = √125, which is an irrational number and must be estimated at 11.2 m.
10^2+5^2=c^2 ; c = 125 m, which is a rational, whole number
5^2+x^2=10^2 ; x = √75 m, which is an irrational number and would be estimated to be 8.7 m.
5^2+x^2=10^2 ; x = 75 m, which is a rational, whole number
