# The angle of elevation of the Sun when the length of the shadow of a pole is equal to its height is :

- 60
^{o} - 30
^{o} - 45
^{o} - 90
^{o}

**Answer: (3) 45 degree**

**Explanation:-**

For answer look in below diagram according to question,

tan A = BC/AB

tan A = H/H

= 1

tan A = tan 45

A = 45 degree.

Then, the value of the elevation of the sun when the length of the shadow of a pole is equal to its height is 45 degree.

Hence, the correct answer is option (3) 45 degree.
