Answer:
Step-by-step explanation:
√3Cosec20° - Sec20°
=> √3/Sin20° - 1/Cos20°
=> 2(√3/2/Sin20° - 1/2/Cos20°)
=> 2(Sin60°/Sin20° - Cos60°/Cos20°)
=> 2( Sin60°Cos20° - Cos60°Sin20°)/Sin20°Cos20°
=> 2(Sin(60°-20°)/Sin20°Cos20°)
=> 2Sin40°/Sin20°Cos20°
=> 2Sin2(20)/Sin20°Cos20°
=> 2*2Sin20°Cos20°/Sin20°Cos20°
=> 4Sin20°Cos20°/Sin20°Cos20°
=> 4
