What is the sin225 degrees + tan45 degrees?

What I did was:

sin(180+45) which would be 0 and the square root of 2/2 respectively.

Then the tan of 45 is 1...

When I tried to solve for it I got squareroot of 2/2 + 1. This was not given as any of the four answer choices so I suppose it is wrong... what is the answer?
