Question : If the angle of elevation of the sun changes from 45° and 65°, then the length of the shadow of a pillar decreases by 10 m. The height of the pillar is:
Option 1: $5\left (3-\sqrt{3} \right)$ m
Option 2: $5\left (\sqrt{3}+1 \right)$ m
Option 3: $15\left (\sqrt{3}+1 \right)$ m
Option 4: $5\left (3+\sqrt{3} \right)$ m
