3. Trigonometry (from Greek trigōnon "triangle"
+ metron "measure") is a branch of mathematics that
studies triangles and the relationships between their
sides and the angles between these sides. The
objective of this assignment is to apply the knowledge
of trigonometry in finding the height of real-life
structures that are too tall to be measured by ruler.

10. Trigonometry can be used to find the height of
object that are too tall to measure by ruler and it can
also be used to find the angle of elevation. The value is
then applied in real life for significant use. There are
several formulas in trigonometry to find different
values of different sides or angles. Trigonometry is very
useful especially for architects to measure for
renovating a building.
