Question

ą.
A vertical pole is 10m high. A ladder is placed against the vertical pole, whose
length is 20m. Find the inclination made by the ladder with the pole
[2M)​

Answer 1

Answer:

Step-by-step explanation:IN ΔABC,

SinФ=AB/AC

⇒SinФ=P/H

⇒SinФ=1/2

⇒SinФ=Sin30°            {∵sin30°=1/2}

comparing both sides

Ф=30°

Hence, the inclination made by the ladder with the pole is 30°
