Jane and anne are at a garage sale, and they are both buying clocks for their collections. when they leave, jane has twice as many clocks as anne does. then jane picks up 4 more at another sale on the way home. so she has 10 all together. how many clocks did anne buy?

Solution:

Let number of clocks does Anne possess when she and Jane leave shop

         = p clocks

Number of Clocks possessed by Jane when she and Anne left shop

           =  2 p clocks

Number of clocks bought by Jane while travelling from garage to home

        = 4 clocks

Total Clocks does Jane possess currently = 10

→→→Expressing the above statement in equation form

→2 p + 4 = 10

→ 2 p = 10 - 4  [Bringing variable on Right side of equation]

→2 p = 6

→p = 3     ⇒ [Dividing both side by 2]

Number of clocks bought by Anne when she was in garage = 3 clocks

Orthographic Projection is used for making the projects but Isometric Projection is used to have better understanding of the object.

Orthographic drawings are typically two dimensional views of an object. For instance, if you were designing a table, you would draw a top view, side view and a bottom view. Should these three views not fully explain the design of the table other views would need to be drawn. When drawing an perspective view in an orthographic manner, you would utilize a 45 degree triangle for the lines that extend back or forward from the vertical lines. This type of perspective is not a true perspective because you can measure the true length of all the details shown. An isometric drawing is meant to depict a 3D image of an object in what appears to be a perspective view. However, similar to an orthographic perspective, all of the lines in an isometric drawing can be measured to their true length. What makes it different from an orthographic perspective is that its angled lines are drawn at 30 or 60 degrees or divisions of them. Drawing this by hand you would use a 30/60/90 triangle.

In either case, both types of perspectives can be accurately measured with a ruler in order to know the objects measurements.
