Question
Is this statement always, sometimes, or never true?If m∠K is between 50° and 60°, then sin(K)=cos(K).alwayssometimesneverSubmit
Solution
The statement is never true. The sine and cosine of an angle are only equal when the angle is 45°. Since m∠K is between 50° and 60°, sin(K) cannot equal cos(K).
