Let us take the scenario in the form of a right triangle, where the height of the pole is represented as AB, the shadow of the pole is represented as BC. Let 
∠ C be the angle of Elevation.
So, We know that,
Tan Ф = Opposite / Adjacent
=> Tan Ф = 15 / 15 √ 3
=> Tan Ф = 1 / √ 3
We know that, Tan 30° = 1 / √ 3
So we can say that, Ф = 30°
Hence the angle of Elevation of the sum at that time was 30°.
