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 !
