Hello, Jaom!

Did you make a sketch?

In a regular heptagon, there are two diagonals with different lengths.

How long is the longer one if the shorter one is 5.0 cm?

The answer is 6.2 cm.

Consider the upper "half" of the heptagon.

Code:B C o * * * o * 5θ θ * 4θ* * * * * * * * θ * 5 * * * θ 2θ * o * * * * * * * o A x D
