Equilateral means that the 3 sides are equal length. For this to happen, the triangle needs to also have 3 equal angles, but it is mentionned that it has an obtus angle, therefore, not all angles are the same, meaning the 3 sides also aren't equivalent.

the triangle isn't equilateral

Debbie cut a cord into sixths . She used five of the to make necklaces . She used equal lengths of the remaining cord for each o
Brut [27]
So she used \frac{5}{6} of the cord to make necklaces.
1- \frac{5}{6} = \frac{1}{6}

She splits the \frac{1}{6} length into 4 equal lengths.
To divide a fraction by a fraction, you multiply it by its reciprocal.
\frac{1}{6} ( \frac{1}{4})
=\frac{1}{24}

She used \frac{1}{24} of the original chord to make each bracelet.
