Evaluat \frac{\sin 36^\circ}{\cos 54^\circ}-\frac{\sin 54^\circ}{\cos 36^\circ}

SSC CHSL Model Paper 12

Question : 71 of 100

Marks: +1, -0

Evaluat

{\sin 36°}/{\cos 54°}-{\sin 54°}/{\cos 36°}

Solution:

{\sin 36°}/{\cos 54°}-{\sin 54°}/{\cos 36°}

{\sin(90-54)°}/{\cos 54°}-{\sin(90-36)°}/{\cos 36°}

{\cos 54°}/{\cos 54°}-{\cos36°}/{\cos 36°}

= 1- 1=0
