The problem ask to find the longest side of the triangle ABC if the longest side of triangle DEF measures 40 units and the best answer among the choices is letter B. 4 units. I hope you are satisfied with my answer and feel free to ask for more .
I'm guessing that the angles at the end are 10 degrees so that would make angle CAB equal 5 degrees. Line AB would be the radius of the "upper cone". Line BC is 12/2 or 6 tangent (A) = BC / AB tangent (5) = 6 / AB AB = 6 / tan(5) AB = 6 / 0.087489 AB =

A geometry transformation is either rigid or non-rigid; another word for a rigid transformation is "isometry". An isometry, such as a rotation, translation, or reflection, does not change the size or shape of the figure.
