The values of CotD and SinC from the information given in the task content are; 15/8 and 15/17 respectively.
What is the value of cotD and sinC?
It follows from the task content that the right triangle has tanC = 15/8 and cosD=15/17.
On this note, it follows from Pythagoras theorem that the other value are as follows;
- sinC = 15/17, cosC = 8/17
- sinD = 8/17 and tanD = 8/15
Hence, it follows that the values of cotD and sinC are; 15/8 and 15/17 respectively.
