Question

1. The map in Figure 1 below shows the map of Bacolod City. The vertices of the
triangle represent the locations of the three landmarks of the City. Vertex C is
University of St. La Salle (USLS), Vertex D is Sebastian Cathedral and Vertex E is Negros
Occidental Government Center (NGC). Using google map and Geogebra, the following
measurements were taken :
a. <C = 70.56°
b. <D = 60.05°
c.h = 2.25 km ( straight distance from USLS to NGC )
Determine the straight distance from USLS to San Sebastian Cathedral, the straight
distance from San Sebastian Cathedral to NGC and angle E which is the angle between
the sides g ( San Sebastian-NGC) and h ( USLS- NGC). These data will be used for the
installation of communication towers. You can find these unknown data using your
understanding of OBLIQUE triangles which is discussed in the next section (III).
