i did draw it and the question is find the value of each variable
do u understand it now?
so they are not parrallel, right?
i dont think so @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
thsnks but i still do not get it @Youngster
Are they separate questions?
ok I have the answer for 1 st one
what is it and how do you do it @ktnguyen1
thank you and can you or someone else help me with the other one
can anyone help me @woksman @amistre64
The first one is correct, x = 36. I didn't look at the second one yet.
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?
does that triangle have equal length sides? if so then all three interior angles are 60 deg
i have no idea the only thing they gave me was what the picture has @snaef999
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
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
how did you get that @ktnguyen1
|dw:1354572720749:dw| then you solve them
ughhhh this is frustrating how do i solve that @tcarroll010 and @ktnguyen1
@hieuvo on the second one
it is hard thanks for helping @hieuvo
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.
thank you verrrrrrryyyyyyy much
