1-1=0
y=0
168/4 to get the bike and the accessories to get 42
42x3=126
These are the two answers you could get
Realize the tangent function has a period of 180°, so when your calculator (or memory) tells you
.. θ = arctan(-1)
.. θ = -45°
you can translate that value into the desired range by adding multiples of 180° to get the two solutions ...
.. θ = 135°
.. θ = 315°
