2025 AISS PRELIMS P2 Q3

Points (A), (B), (C) and (D) are on horizontal ground. (AB=37 ext{ m}), (BC=50 ext{ m}), (AC=62 ext{ m}) and (CD=73 ext{ m}). (angle ADC=52^circ). (A) is due west of (C).

1. Find (angle ABC).[3]
2. The bearing of (E) from (C) is (124^circ). Find the bearing of (C) from (E).[1]
3. Find the bearing of (D) from (A).[3]
4. Point (C) is the base of a vertical flagpole (CF). The angle of elevation of (F) from (B) is (8^circ). Calculate the angle of elevation of (F) from (D).[3]
