The value of the side FD of the building is 242.7 feet
What is trigonometric identity?
Trigonometry is the branch of mathematics that set up a relationship between the sides and angle of the right-angle triangles.
Trigonometric identities are equality conditions in trigonometry that hold for all values of the variables that appear and are defined on both sides of the equivalence. These are identities that, geometrically speaking, involve certain functions of one or more angles.
In the given figure we can see that the height of the building is 75 feet and the angle made by the building at a distance FD is 18 degrees.
To calculate the side FD uses the sin angle property in the right angle triangle.
The sine angle is the ratio of the perpendicular to the hypotenuse for the right angle triangle.
Sin(18)= 0.309
0.309 = 75/FD
FD = 242.7 feet
Therefore, the side FD is 242.7 feet
