`cos25^@-sin25^@=p` then find `cos50^@`

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

If cos25^0+sin25^0=p , then cos50^0 is

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))

cos5^@-sin25^@ is equal to

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

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

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

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