| The angles of elevation of the top of a tower from the top and foot of a pole are respectively 30

^{o}and 45^{o}. If h is the height of the tower and y is the height of the pole, then which of the following are correct?1)

2)

3)

Select the correct answer using the code given below.

A. 1 and 3 only

B. 2 and 3 only

C. 1 and 2 only

D. 1, 2 and 3

### Right Answer is: C

#### SOLUTION

Let the distance between tower and pole be x

⇒ h = x

Now

⇒

⇒

⇒

⇒

⇒

Hence statement (2) is correct

Now

⇒

⇒

Hence statement 3 is incorrect.

So option C will be correct
