The tangent of a 45 degree angle is 1 0 1/2 -1

The answer is 1

reason to this being 1.. is 45 degrees is pi / 4 
tan is composed of sin(x) over cos(x) which angels are sqrt 2 over 2 
when you divide them by each other is the same as multiplying by their 
reciprocals making the answer 1.

hope this helps and give brainliest, id appreciate it
