so they are not parrallel, right?

i dont think so @Youngster
Youngster
  • Youngster
well with the triangle thing, use the property that an exterior angle is the sum of the opposite two interior angles, and solve using the system of equations
anonymous
  • anonymous
thsnks but i still do not get it @Youngster
anonymous
  • anonymous
Are they separate questions?
anonymous
  • anonymous
ok I have the answer for 1 st one

yes @zordoloom

x=36

  • anonymous
what is it and how do you do it @ktnguyen1

thank you and can you or someone else help me with the other one
anonymous
  • anonymous
can anyone help me @woksman @amistre64
anonymous
  • anonymous
The first one is correct, x = 36. I didn't look at the second one yet.
anonymous
  • anonymous
okay thanks and tell me when you get the second one

I can't work with the second one because I don't understand your diagram. Doesn't make sense to me the way it is written.

Is that z - 13 and z + 10?
anonymous
  • anonymous
yes @tcarroll010
anonymous
  • anonymous
does that triangle have equal length sides? if so then all three interior angles are 60 deg
anonymous
  • anonymous
i have no idea the only thing they gave me was what the picture has @snaef999
anonymous
  • anonymous
I think you need to assume they are the same. I think that is the only way to do it. Otherwise you dont have enough info.

x=59 y=49 w=72 z=121
anonymous
  • anonymous
z - 13 + w = 180 z + 10 + y = 180 x = 180 - (w + y) x + z = 180 Substitute equation #3 into equation #4. Use equations #1, #2, and #4 for 3 equations in 3 unknowns (z, y, and w). Solvable.

i dont understand what your saying @tcarroll010
anonymous
  • anonymous
how did you get that @ktnguyen1
anonymous
  • anonymous
|dw:1354572720749:dw| then you solve them
anonymous
  • anonymous
ughhhh this is frustrating how do i solve that @tcarroll010 and @ktnguyen1
anonymous
  • anonymous
@hieuvo on the second one

  • anonymous
it is hard thanks for helping @hieuvo

  • anonymous
z - 13 + w = 180 z + 10 + y = 180 x = 180 - (w + y) x + z = 180 Substitute equation #3 into equation #4. Use equations #1, #2, and #4 for 3 equations in 3 unknowns (z, y, and w). Solvable. z - 13 + w = 180 z + 10 + y = 180 180 - (w + y) + z = 180 So, we have: z + w = 193 z + y = 170 z - w - y = 0 Adding equation #2 to equation #3: z + w = 193 z + y = 170 2z - w = 170 Adding equation #1 to #3: z + w = 193 z + y = 170 3z = 363 So, z = 121. Easy to find the others now.
