Question

An aeroplane flying at a height of 3000 metres above the ground passes vertically above another plane at an instant when all angles of. elevation of the two planes from the same point on the ground are 60° and 45° respectively. The height of the lower plane from the ground (in metres) is (A) 1000 √ 3 m (B)  (1000 /√ 3)m (C) 500 m (D) 1500(√ 3 +1)m.

Tardigrade Admin · Accepted Answer

Correct answer is (a) 1000 √ 3 m

$10003 m$

$\frac{1000}{3} m$

500 m

$1500 (3 + 1) m .$

Correct answer is (a) $10003 m$

10003​m

3​1000​m

500 m

1500(3​+1)m.

Correct answer is (a) 10003​m

$10003 m$

$\frac{1000}{3} m$

$1500 (3 + 1) m .$

Correct answer is (a) $10003 m$
