If `cos 25^(@) + sin 25^(@) =p`, then: `cos 50^(@)=`

If cos25^(@)+sin25^(@)=p , then cos 50^(@) is

cos 25^(@) - cos65^(@) =

cos25^(@)-sin25^(@)=p then find cos50^(@)

If cos25^(0)+sin25^(0)=p, then cos50^(@) is (a) sqrt(2-p^(2))(b)-sqrt(2-p^(2))(c)p sqrt(2-p^(2))(d)-p sqrt(2-p^(2))

cos 5^(@) - sin 25^(@) is equal to

cos 5^(@) - sin 25^(@) is equal to

If cos 25^0 + sin 25^0 = p , then cos 50^0 is equal to

If cos25^(0)+sin25^(0)=K, then cos50^(@) is equal to

If cos 25^0 + sin 25^0 = K , then cos 50^0 is equal to
