MATH PROBLEMS
Part 2: Problems 3.26 and 3.27
PROBLEM 3.26 Draw the following sheet metal part using
CADD software. Use the entry method of your choice. Space is
provided in which you can write the coordinate values needed
to draw a line to each point—or use a separate sheet.

PROBLEM 3.27 The following property plat has been given
to you in the form of a sketch with included angles. You are to
draw the property plat full size using the dimensions given.
Do not use decimal values for angles or distances. Space is
provided in which you can write the coordinate values needed
to draw a line to each point. Write your answers using a polar
coordinate notation. For example, a line 879-30 long, at an
angle of 658, is written @ 87930,65.
