mAB
= 2/(2+3+4) * 360 deg
= 80 deg
mBC
= 3/2 * mAB
= 120 deg
mCA
= 4/3 * mBC
= 160 deg
idek how to solve m angle A,B,C from just these informations..... sry......
??
What do you mean by this?
Window XP does not suck it can do 2^100 and show the answer properly and not using scientific notation......
Personally love Window 7 though XD
8^2 - 2^2
= 64 - 4
= 60 :D
The first sentence indicate that the width of the rectangle = 2 x 6 = 12.
2nd sentence indicates that length = 10 + 6 + 6 = 22
Area = 22 x 12 = 264
The surface area of this thing is just a 3 x 3 x 1 box surface area minus 2 faces because there are still squares in the hole.
Surface area
= (3 x 3) x (3 x 3) x 2 + 3 x (3 x 3) x 4 - 2 x 3 x 3
= 252 square centimeters
Noice.
Melody may put this post into the Sticky topic like mine!!
My post teaches new members how to use LaTeX!!
Great job on doing this :D

Use Pythagoras theorem to find the lengths of blue lines.
Total length
= 4/2 + 6/2 + 8/2 + √(42)2+(62)2+√(82)2+(42)2+√(62)2+(82)2
= 2 + 3 + 4 + √13 + 2√5 + 5
= 14 + sqrt(13) + 2sqrt(5)
8k/2 = 12.5% * 8 * 9
4k = 9
k = 2 1/4 :)
