Answer:
Sin (4.25π)= 0.7071
Cos(4.25π)= 0.7071
Tan(4.25π)= 1
Step-by-step explanation:

Sin, Cos and Tan of 45º angle is the same with 1,2 or more circumferences.
So the result is the same for 45º angle.
So:

The lowest common denominator among these would be 3

Answer:
The fraction of the book Omarion read over the weekend=3/5
Step-by-step explanation:
Step 1
Determine the initial number of pages in a book that's remaining as follows;
Initial number of pages remaining=9/10 of the book
Step 2
Determine fraction of the book read over the weekend as follows;
fraction read over the weekend=fraction of the remaining read×initial number of remaining pages read
where;
fraction of the remaining read=2/3
initial number of remaining pages read=9/10
replacing;
fraction read over the weekend=(2/3)×(9/10)=3/5
The fraction of the book Omarion read over the weekend=3/5
