The city council is planning a new city park on a triangular plot of land
formed by three intersecting streets.
the designer placed the triangle on a grid to determine the side lengths and
angle measures needed for the purchase and placement of a fence
surrounding the park. each unit on the grid is one inch, which represents
20 feet of actual length.
the measure of angle cab in the designer’s diagram is (5x + 1)°, and the
measure of angle acb is (3x + 12.5)°.

create a report that provides a detailed
description of the park. include the following in your report:
• the actual side lengths of the triangular plot of land
• the type of triangle formed by the intersection of the three streets
• the amount of fencing needed to surround the city park
• the actual measure of each angle of the triangle
