Figure 1-13 A flower bed project Ex 1.10 A gardener has a rectangular plot measuring 3.0 m x 4.0 m. She wishes to use half of this area to make a triangular flower bed. a. Which one should she use? b. In laying out the flower bed, the gardener decides to use a right triangle. Wishing to line the sides with rows of stones, she wants to known the total length of the triangle sides and the values of the acute angles of the triangle.

Figure 1-23 Measuring with lines of sight 72.A student wants to determine the distance from the lakeshore to a small island. He first draws a 50-m line parallel to the shore. Then, he goes to the ends of the line and measure the angles of the lines of sight from the island relative to the line he has drawn. The angles are 30 o and 40 o. How far is the island from the shore?
