45 degrees
0 is your answer tan(45)=1 and arccos(1)=0
If y = 2x+1 is a tangent line to the circle 5y^2 +5x^2 = 1 then the point of contact is at (-2/5, 1/5) because it has equal roots
Tangent is determined by the ratio of the side opposite the angle over the one adjacent to it. In a 45-45-90 triangle, the ratio of these sides is 1. This is because the side opposite one of the 45 degree angles is adjacent to the other, and vise versa.

tan 45° = 1
The angle you seek is 45 degrees. The angle whose tangent is 1 can be written arctan(1) = 45 degrees.

Yes. The tan of 45 degrees is 1.
Cotangent 32 equals tangent 0.031
45 degrees
If y = 2x+1 is a tangent line to the circle 5y^2 +5x^2 = 1 then the point of contact is at (-2/5, 1/5) because it has equal roots
That would be an isosceles right triangle with sides of 1, 1, and the square root of 2. 1/1=1.
