#### Question

The top of a ladder reaches a pcint on the wall 5 m above the ground. If the foot of the ladder makes an angle of 30° with the ground, find the length of the ladder.

#### Solution

Here, AC is the ladder and AB is the point which is 5 m above the ground.

In ΔABC,

sin30° = `"AB"/"AC"`

⇒ `1/2 = 5/(AC)`

⇒ AC = 10

Thus , the length of the ladder is 10 m.
