Question

A monkey climbs an 8 m long pole which has its top resting on a wall and the other end making an angle of 30° with the ground. Find the distance between the foot of the pole and the wall​

Answer 1

Step-by-step explanation:

The monkey climbs 6 m in a minute and falls 3 m in next the minute. So, effectively monkey climbs 6 - 3 = 3 m in every 2 mins that is essentially, 1.5 m in a minute. Now, with this speed monkey will travel 15 m in 10 minutes. And in the next minute, the monkey will travel 6 m and cover total distance of 21 m.
