Me with this one asap and you
(will mark brainlest)

Sam claims that cos x =sin y if x and y are congruent angels. is sam correct ?

3382-299=3383- ? fill in the blank?

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions. a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0
