It is equal to 1 (one).

A 45 degree angle produces a vertical rise equal to the horizontal run, producing an isosceles right triangle with a hypotenuse of (sq rt 2)*a where a is the height/side. Opposite over adjacent = a/a = 1.

Which angle has a tangent of 1?

Oh, dude, the angle that has a tangent of 1 is 45 degrees or π/4 radians. It's like the cool kid at the math party, always hanging out with a value of 1 and making all the other angles jealous. So, if you wanna be in the tangent club, just remember 45 degrees is where it's at.

Explain why the tangent of 45 equals 1?

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.
