Answer:
Undefined or No solution
Step-by-step explanation:
Because this line is a straight, vertical line, it means that the slope is undefined, or no solution. Any time you see a straight line going up and down, this will be true. However, if you see a horizonal line, this will not be true.
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:

Answer:
I think its 40 I could be wrong
Step-by-step explanation:

200/2= 100
100/2 = 50
50/2 = 25
