You can put this solution on YOUR website! How to do it: If theta and beta belong to Q1, and cot theta = 12/13,
sin beta = √ 2/2, tan (theta + beta) is equal to:
***
letx=theta
lety=beta
Identity: tan(x+y)=
..
cotx=12/13 (given)
tanx=13/12
..
siny=√2/2 (working with a 45˚ right triangle)
tany=1
..
tan(x+y)=
ans: c)25
