Jaxon is creating a mosaic design on a rectangular
table. He has added two pieces to one of the corners.
The first piece has an angle measuring 38° and is
placed in the corner. A second piece has an angle
measuring 27° and is also placed in the corner. Draw a
diagram to model the situation. Then, write an
equation, and use it to determine the measure of the
unknown angle in a third piece that could be added to
the corner of the table.
