It is A because when you add the amount of your purchases and you subtract it from 102.35. You get a negative number. Then you add that negative number to 25 and 24.75.
Answer:
Therefore the angle of intersection is 
Step-by-step explanation:
Angle at the intersection point of two carve is the angle of the tangents at that point.
Given,

and 
To find the tangent of a carve , we have to differentiate the carve.

The tangent at (0,0,0) is [ since the intersection point is (0,0,0)]
[ putting t= 0]

Again,

The tangent at (0,0,0) is
[ putting t= 0]

If θ is angle between tangent, then






Therefore the angle of intersection is
.
Answer:
.12314
Step-by-step explanation:
5.2+4.8= 10
So it has to be 20 I think
