Question

A ladder 13m long rests against a vertical wall. if the foot of the ladder is 5m from the foot of the wall, find the distance of the other end of the ladder from the ground​

Answer 1

base = 5m.

hypotenuse= 13 m.

by PGT,

H²=L²+B².

(13)²=l²+ (5)²

169=l²+25

169 -25=l²

144 = l².

l=√144

l=±12.

neglecting -12

length is 12m .

Answer 2

Answer:

12m

Step-by-step explanation:

let the other side be x m

x^2=13^2-5^2

x^2=169-25

x^2=144

x=12 m
