What are the sine, cosine, and tangent of θ = 7 pi over 4 radians?

sin θ = negative square root 2 over 2; cos θ = negative square root 2 over 2; tan θ = 1

sin θ = negative square root 2 over 2; cos θ = square root 2 over 2; tan θ = 1

sin θ = square root 2 over 2; cos θ = negative square root 2 over 2 tan θ = −1

sin θ = negative square root 2 over 2; cos θ = square root 2 over 2; tan θ = −1

Asays "we are both knaves" and b says nothing. exercises 24–31 relate to inhabitants of an island on which there are three kinds of people: knights who always tell the truth, knaves who always lie, and spies (called normals by smullyan [sm78]) who can either lie or tell the truth. you encounter three people, a, b, and c. you know one of these people is a knight, one is a knave, and one is a spy. each of the three people knows the type of person each of other two is. for each of these situations, if possible, determine whether there is a unique solution and determine who the knave, knight, and spy are. when there is no unique solution, list all possible solutions or state that there are no solutions. 24. a says "c is the knave," b says, "a is the knight," and c says "i am the spy."

Me with geometry ! in this figure, bc is a perpendicular bisects of kj. dm is the angle bisects of bdj. what is the measure of bdm? •60° •90° •30° •45°
