Question 1034092
Thinking just about signs, it is given that 
sin(t) is positive and cot(t) is negative.
--------------------
The sin function is positive in the
1st and 2nd quadrants
--------------------
The cot function is negative in the
2nd and 4th quadrants
--------------------
{{{ t }}} must be an angle in the 2nd 
quadrant
The horizontal component is {{{ 4 }}}
since {{{ 5^2 - 3^2 = 4^2 }}}
--------------------
{{{ tan(t) = -3/4 }}}
