Calculus problem by Blueishere on 11-20-2006 at 02:47 AM
Not sure if this is the right place but if anyone can help it would be really great.
A rain gutter is to be constructed from a long metal sheet of width 36cm. The gutter is 20m long and is constructed by bending up the edges of the sheet through an angle x to form a symmetrical shape with a cross section.
(1)The dimensions of the cross-section of the gutter are in the ratio 1:1:1
(2)The dimensions of the cross-section of the gutter are auch that the base is 16cm
All I know is that I have to use calculus to solve and that integration is not necessary
Please help me!

Assuming that the cross-section is a trapezium, the angle x is 19.47°. No calculus was needed, just some basic trigonometry.
If the cross-section is meant to be something else, then I'll have another go.
