First problem

Hello ! It's the first mathematical problem, write by Alice and Deborah : <!-- @page { size: 21cm 29.7cm; margin: 2cm } P { margin-bottom: 0.21cm } -->

Draw a circle with a diameter [AB] which measures 8 cm. Draw the circle's tangent going through the point A.

Then draw the triangle BOC. OC=7,3cm and BC=6,1. Draw the line (BC).

D is a point in the tangent and AD=9,52cm. The triangle ADE is rectangle and AE=8,64cm.

Draw (AE) and (DE) which cut (BC) in F and G.

And now, find the [ED]'s length.

Good luck !
