The angle of elevation of the top of a tower 24√3 m high from two points on the level ground on its opposite sides are 45° and 30°. What is the distance (in m) between the two points |
(72 - 24\(\sqrt { 3}\)) m (24\(\sqrt {2}\) + 72) m (24\(\sqrt { 3}\) + 72) m (24\(\sqrt { 3}\) + 48) m |
(24\(\sqrt { 3}\) + 72) m |
tan 45° 1 : 1 ↓ 24\(\sqrt { 3}\) ↓ 24\(\sqrt { 3}\) tan 30° 1 : \(\sqrt { 3}\) ↓ 24\(\sqrt { 3}\) ↓ 72
Total distance = (24\(\sqrt { 3}\) + 72) m |
