`cos110^@ + sin20 =`

The value of sin20^@ cos70^@+ sin70^@ cos20^@ is: sin20^@ cos70^@+ sin70^@ cos20^@ का मान क्या होगा ?

What is the value of (cos 10 ^(@) + sin 20^(@))/( cos 20^(@) - sin 10 ^(@))?

Prove that, (cos 20^(@) + sin 20^(@))/(cos 20^(@) - sin 20^(@)) = tan 65^(@)

Assertion (A) : cos20^(@) - sin20^(@) gt 0 Reason (R) : If theta in R, cos theta - sin theta gt 0 choose the correct answer

A=cos20^(@) - sin 20^(@) ,B=cos100^(@) + sin100^(@) , C= cos""(5pi)/6+ sin""(2pi)/3 then the ascending order is

cos110^@*cos70^@-sin110^@*sin70^@ = …………….
