Giselle wants to know the height of a certain house (in meters) while roaming around the
suburbs of Cagayan de Oro City, but Giselle does not have the tools to measure the
building directly. What she does know is her height (1.5m), the distance between her and
the building (adjacent) is 9m, and the angle of elevation from her head to highest point of
the house's roof (75 degrees). Calculate the height of the house (considering Giselle's
height), and the hypotenuse with respect to Giselle's head to the highest point of the
house's roof.
Afterwards, check the value of the height of the house using sine, cosine and
tangent.
