Find the exact value of cot theda if theda is in standard position and (7,2) is on the terminal side of Theda

When an angle is in its standard position, the vertex coincides with the origin, the initial side with the xaxis. If the terminal side passes through (7,2), then the angle is in the second quadrant.
For angles in all quadrants, cot(θ)=1/tan(θ).
Since tan(θ)=2/(7)=2/7,
cot(θ)=1/(2/7)=7/2.
