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 coordinates at the midpoint of any line are the averages of the coordinates at the end-points. So 7 has to be the average of 10 and k .
(1/2) (10 + k) = 7
5 + k/2 = 7
k/2 = 2
<em>k = 4</em>
