We are looking at a right triangle with both legs = 1. This is an isosceles right triangle and so the base angle are each 45 degrees. So tan 45 degrees = 1

45 degrees.
Think of an isosceles right triangle(angles 45,45,90).
The 2 legs are congruent and tan 45 is the ratio
of the 2 legs, so it is 1.

tan(x) = sin(x)/cos(x)
so tan(x) = 1 whenever sin(x)/cos(x) = 1. That happens when sin(x) = cos(x); i.e. at 45 degrees.
