Use sind() and cosd() to create the x and y endpoints of the line, x1,x2,y1,y2. Then call
line([x1,x2], [y1,y2], 'Color', 'k', 'LineWidth', 2)
Sounds like homework, so give it a try yourself. Have a for loop over all angles. Here's a start:
for angle = 1 : 20 : 360
x1 = lineLength * cosd(angle......
line([x1,x2], [y1,y2], 'Color', 'k', 'LineWidth', 2)
hold on;
end
