HW1.4. Illustrate a vector

The origin of the drawing canvas below is the left-top corner. Each square has unit 20.

Insert a vector with tail at position $(100, 180)$. The vector should make an angle $\alpha = 30^o$ counter-clockwise with respect to the horizonal axis.

(The expected tolerance is 1/2 square grid for position and 10 degrees for angle.)
