you're trying to prove that Fawun.. HAHA
Draw a perpendicular line from A to line BC. Then prove RHS, so corresponding angles in congruent triangles are equal.

Me =) . Mostly beyond godlike in all my Dota games, yet forever stuck in ~1350 elo for LoL. But saying that, I play on BA, which i've heard have a lot of baddies in them.

Water after 5 hours
=800x5
=4000L
let a be height/depth
Volume of diving pool
=6x4xa
=24a m^3
=24000a L
equate: 24000a = 4000
a= 1/6 m
Yes. When I did the Hurlstone exam in Year 9, they gave me an extract where I had to answer short questions, then had to write a report where I could look back at the info. It was about rats :P
Good luck on the test!
