Question
Is this statement always, sometimes, or never true?If m∠D is greater than 35°, then cos(D)=sin(D).alwayssometimesneverSubmit
Solution
The statement is never true. The only time when cos(D) equals sin(D) is when D equals 45°. Therefore, if m∠D is greater than 35°, it does not necessarily mean that cos(D) equals sin(D).
