Question

96 sin 65 ° sin 35° sin 80° / sin20° + 2 Sin 80° cos 30°

Answer 1

(96 sin 65 ° sin 35° sin 80°) / (sin20° + 2 Sin 80° cos 30°)

= (96x0.91x0.57x0.98) / (0.34 + 2x0.98x0.87)

= 48.8 /(0.34 + 1.71)

= 48.8/2.05

= 23.8


(96 sin 65 ° sin 35° sin 80°) / (sin20° + 2 Sin 80° cos 30°) = 23.8


We get Sin and Cos using calculator or mathematical table
