Explanation:
At sunset, sun is in the west, shadows fall east. Lopa's shadow falls on Kritika's right. For Kritika's right to be east, Kritika must be facing north. (Lopa then faces south, and her shadow east falls on Kritika's right side.)

Explanation:
Let IT be (0,0) and ECE be (0,18). Civil is 30m from IT in the NW. Mechanical is West of ECE, meaning its y-coordinate is 18. This aligns horizontally. Civil is 32m North of Mechanical or fits into a standard 18-24-30 right triangle (where base is 24m, height 18m, hypotenuse 30m). Thus, the distance along the horizontal axis mapping to Mechanical is 24m.
