(Hint: What is the relationship between <ABH and <ABF? They share a straight line...
Then what is the relationship between <ABF and <BFG? Then what is line FC again?
For a hint, read the yellow words at the bottom of the slide, but always try some of
your own thoughts first!

Coralie notices a 10mm x
18mm white spot in the
middle of the stone
when she goes to buy it so
it's not 100% pure onyx.
The jeweler offers her a
deal where she only pays
the same percentage of the price
that the pure onyx represents of the stone. If the ring
costs $1500, how much will Coralie pay before taxes?
Hint: What is the area of the white spot?
What is the area of the whole stone?
What % of the whole stone is pure onyx (black)?
A                  -shaped black onyx stone is made into a
ring.              The stone JUST fits inside a pink,
rectangular box that measures 4cm x 6cm.
