Step-by-step explanation:
A two-dimensional figure is a flat figure that is described by its length of sides only. It can be obtained from a three dimensional solid when sliced or truncated.
Truncation is the process of cutting a solid with respect to a given plain. Therefore, when a three dimensional solid is truncated, the face forms a two dimensional figure. An example is when a cube is truncated horizontally, a square can be obtained at the surface.
Answer:
Step-by-step explanation:
498/26 = 19 with a remainder of 3
so each group will have nineteen students but you need 22 more to make all groups have 20 students
498 + 22 = 520
520/26= 20
Well.. the equation for the interior angles of a polygon is 180(n-2). So it could possibly be 180.
Hope I could help.
Answer:
Since m<BCA=m<CAB=55°, it follows that |AB|=|AC|, this means triangle ABC is isosceles.
Step-by-step explanation:
In the diagram AB is parallel to DC.
This means that, by the alternate interior angles theorem?
Also the sum of angles in a triangle should be 180° .
Since m<BCA=m<CAB=55°, it follows that |AB|=|AC|
Hence triangle ABC is isosceles.
