First of all, lets say a is the shortest side, b the second and c the longest.
We can therefore write the following equations:
a=(1/2)b=(1/3)c
-> b=2a and c=3a (in order to have the three of them with the same variable)
Perimeter = a + b + c
P= a + 2a + 3a
P=6a
Now if we compare c to the perimeter (using ratio) we get:
c/6a = 3a/6a = 1/2
Therefore, the longest side is equal to half the perimeter
Answer:
Step-by-step explanation:
Given that:
Little Gull Island Lighthouse shines a light from a height of 91 feet above the sea level.
The angle of depression is unknown.
Distance of the point at sea surface from the base of lighthouse is 865 ft.
This situation can be modeled or can be represented as the figure attached in the answer area.
The situation can be represented by a right angled in which we are given the base and the height of the triangle.
And we have to find the value of (Because they are the internal vertically opposite angles).
Using tangent ratio:
Therefore, the angle of depression is:
