ground on placing it against a wall. Find the distance of the foot of the ladder from the wall.

OPTIONS:
A. 85 m
B. 92 m
C. 96 m
D. 82 m

​

Answer 1

Answer:

96 m

Step-by-step explanation:

H = 120m

P = 72 m

B = ????

Pythagoras Theorem ----:

H^2 = P^2 + B^2

B^2 = H^2 - P^2

B^2 = (120^2) - (72^2)

B^2 = (14400) - (5184)

B^2 = (9216)

B = 96 m
