well, let's start off with the first problem (#17) the shape is a quadrilateral, so we know that all the angles add up to 360 x + x + 95 + 35 = 360 solve for x

95+35= 130 360-130= 230
anonymous
  • anonymous
\[230\div2=115\]
Vocaloid
  • Vocaloid
yup, so x = 115
Vocaloid
  • Vocaloid
ready for #18?
anonymous
  • anonymous
Yup :)

well, this is a parallelogram, so we know that opposite sides are equal all we have to do is write 3x + 12 = 18 and solve for x
anonymous
  • anonymous
Wait I know the answer.... 18 is 2
Vocaloid
  • Vocaloid
yup, x = 2
Vocaloid
  • Vocaloid
ready for #15?
anonymous
  • anonymous
yes
Vocaloid
  • Vocaloid
well, again, this uses the same rule: opposite sides are equal so 3x - 2 = 25 solve for x
anonymous
  • anonymous
x=9?
Vocaloid
  • Vocaloid
yup, ready for the last one?
anonymous
  • anonymous
Yes. ^.^

this is a quadrilaterial, so we use the 360 rule again 3x + 2x + 44 + 86 = 360 x = ?
anonymous
  • anonymous
Idk..... I'm struggling with this one
Vocaloid
  • Vocaloid
hm, ok, let's start by combining like terms 3x + 2x = ?
anonymous
  • anonymous
3x+2x=5x 44+84=130
anonymous
  • anonymous
360-130=230
Vocaloid
  • Vocaloid
good so far. right now we have 5x = 230 so x = ?
anonymous
  • anonymous
230/5=46
anonymous
  • anonymous
I think
Vocaloid
  • Vocaloid
yupp so x = 46 that's it
