Question

if xsin45°cos²60°= tan²60°cosec30°/sec 45°cot²30°, then x = ?​

Answer 1

Answer :

x(sin45°).(cos²60°)

={(tan²60°)(cosec30°)}/{(sec45°)(cot²30°)}

x(sin45°)(cos60°)²

={(tan60°)²(cosec30°)}/{(sec45°)(cot30°)²}

x(1/√2)(1/2)²

={(√3)².(2)}/{(√2).(√3)²}

x/4√2=6/3√2 , x/4 = 6/3

x/4 = 2 , x = 2 x4 , x = 8
