a) I would begin by stating the lengths of the 3 sides of the triangle.
Can I get some help with this question?
Let a=(1, 5) and b=(2,2) and let c=(x,0) with x >= 8/3 be a point along the x-axis.
(a) Find the maximum possible angle at c in the triangle abc.
(b) Find the maximum possible length for the shadow along the y-axis cast by the line
segment ab when a light is placed at point c.
How did you obtain these measures for the side lengths? What method did you use for optimization?
edit: I see you edited your post. I am glad this was a mistake, as they were wrong.
