FIND X, Y, AND Z
anonymous
  • anonymous
Okay so do you see the angle where it says 125 in the bottom left?

Looking for something else?

yes
anonymous
  • anonymous
That angle is supplementary to x so \[180-125=?\]
anonymous
  • anonymous
55?
anonymous
  • anonymous
Yes and since this triangle is an isosceles x and z are congruent to each other so|dw:1436372583244:dw|
anonymous
  • anonymous
ok thanks! now whats y?
anonymous

What do the interior of a triangle's angles add up to?
anonymous
  • anonymous
110?
anonymous
  • anonymous
180?
anonymous
  • anonymous
180 yes so\[55+55=110\] \[180-110=?\]
anonymous
  • anonymous
70?
anonymous
  • anonymous
Yes now to check your work \[55+55+70=?\]
anonymous
  • anonymous
180
anonymous
  • anonymous
what about this one? find x and y

@Venice-Gribbin im not sure how to answer this question. Little help?
anonymous
  • anonymous
find x and y is it 35 for both?
1 Attachment
anonymous
  • anonymous
Remember that the 110 and x are supplematary so 180-110=?
anonymous
  • anonymous
70?
anonymous
  • anonymous
Correct
anonymous
  • anonymous
So now, what's 70+90?
anonymous
  • anonymous
160
anonymous
  • anonymous
x=y+15 y=x-15 this is all i can contribute.

anonymous
  • anonymous
160 now minus 180 equals?
anonymous
  • anonymous
I summon @iGreen for reference.
anonymous
  • anonymous
20?
anonymous
  • anonymous
So that missing angle or Y=20
anonymous
  • anonymous
okay so y is 20 but whats x?
anonymous
  • anonymous
70 because 180-110=70 and those two angles are supplmentary
anonymous
  • anonymous
okay thanks! i have like three more questions
anonymous
  • anonymous
Okay shoot them :)
anonymous
  • anonymous
what is the value of x and y

Um, which question are we looking at exactly?
anonymous
  • anonymous
find x and y
1 Attachment
anonymous
  • anonymous
The one above and the one that Venice summoned you for
iGreen
  • iGreen
Okay, all angles are equal..it's an equilateral triangle.
anonymous
  • anonymous
ok
iGreen
  • iGreen
180 / 3 = ?
iGreen
  • iGreen
All equilateral triangles have the same angle measurement.
anonymous
  • anonymous
60
anonymous
  • anonymous
so both angles are 60?
iGreen
  • iGreen
All 3 angles are 60. So we can write: y - 10 = 60 x + 5 = 60
iGreen
  • iGreen
Solve both for 'x' and 'y'
anonymous
  • anonymous
70 and 65?
anonymous
  • anonymous
i mean 55?
anonymous
  • anonymous
is that correct?
anonymous
  • anonymous
?????
anonymous
  • anonymous
anyone?
anonymous
  • anonymous
@iGreen is that correct?
iGreen
  • iGreen
Yes, that's correct.
iGreen
  • iGreen
y = 70 x = 65
anonymous
  • anonymous
why isnt x 55?
anonymous
  • anonymous
@iGreen ?
iGreen
  • iGreen
Oops, my bad typo..it is 55.
anonymous
  • anonymous
ok thanks!
anonymous
