Easy Geometry
Please help

Description about easy geometry is given below

Step-by-step explanation:

1.The basic geometric objects that create shapes like : points, lines, line segments, rays, and planes. A point is represented by a dot and shows a location in space.

2.Geometry is easier and it was easier to study for. Algebra is more focused on equations while the things covered in Geometry really just have to do with finding the length of shapes and the measure of angles.

3.In two dimensions there are 3 geometries:

4.A point in geometry is a location. ... A point is shown by a dot. A line is defined as a line of points that extends infinitely in two directions. It has one dimension, length. Points that are on the same line are called collinear points.

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.
