Question

If 5 theta and 4 theta are acute angles satisfying sin 5 theta = cos 4 theta, then the value of 2 sin 3 theta-root over 3 tan 3 theta is
(a) 0
(b) 1
(c) 2
(d) 3​

Answer 1

sin 5∅ = cos 4∅

=> sin 5∅ = sin(90 - 4∅)

=> 5∅ = 90 - 4∅

=> ∅ = 10

Value of 2 sin∅ 3∅ - √3 tan3∅

=> 2 sin 30 - √3 * tan 30

=> 2 * (1/2) - √3 * (1/√3)

=> 1 - 1

=> 0
