11.2x+x+(x+8)=180
Combine like terms
3x+(x+8)=180
4x+8=180
180-8=172
4x=172
x=43

12.(x-3)+x+(x+8)+(x-5)=360
Combine like terms
4x-3+8-5=360
-3+8=5
5-5=0
4x=360
x=90

We can split this up into 3 rectangles.  2 vertical ones (8 x 3) and one horizontal one in the middle (5 x (8 - 5)

8 x 3 = 24
24 x 2 = 48

5 x (8-5) = 5 x 3 = 15

now add 48 + 15 = 63 cm^2

Triangle P=27,Q=40,P=33 law of sines round measures to the nearest tenth
nordsb [41]
For the law of sines, you would apply it in this particular problem like so:
Since P is 27, its angle is 33 and Q's length is 40; you would set it up like this
<u />40/SinQ = 27/Sin33, multiply 40 with Sin33, then it would be 40Sin33, then divide it by 27. The result should be 40Sin33/27 = X
