The answer would be $24.55 per oz of gold alloy so rounded up would be $25
The total of all angles are 360 degrees for a parallelogram. One angle is 10 and the one opposite is also 10. B = 340/2=170 degrees
right-handThe triangles are similar if, the ratios of their sides are equal
![\frac{AE}{AC}=\frac{AW}{AL}](https://tex.z-dn.net/?f=%5Cfrac%7BAE%7D%7BAC%7D%3D%5Cfrac%7BAW%7D%7BAL%7D)
![\frac{8+8}{6+6}=\frac{8}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B8%2B8%7D%7B6%2B6%7D%3D%5Cfrac%7B8%7D%7B6%7D)
On the left-hand side
![\frac{16}{12}=\frac{4}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B16%7D%7B12%7D%3D%5Cfrac%7B4%7D%7B3%7D)
and in the right-hand side, we have
![\frac{8}{6}=\frac{4}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B6%7D%3D%5Cfrac%7B4%7D%7B3%7D)
The left-hand side equals the right-hand side; therefore, the triangles are similar.
2 is common factor
2x=2(x)
4=2(2)
ab+ac=a(b+c)
2(x)+2(2)=2(x+2)
