For this case we have by definition of trigonometric relations of rectangular triangles that, the sine of an angle is given by the opposite leg to the angle on the hypotenuse of the triangle. Then according to the figure we have:
We cleared CA:
Answer:
Option A
Answer:
Precision = 0.625
Recall = 0.5
Step-by-step explanation:
Data:
Let: total documents = 10
relevant documents = 5
if 2 documents are removed, the total number of documents remaining will be
documents remaining = total - 2 documents
= 10 - 2
= 8 documents
therefore, the precision will be =
Recall =
