Answer:
The length of the third side of given triangle lies between 6.5 and 19.9.
Step-by-step explanation:
The law of cosine is as follows
---------------1
⇒ a and b are the given sides of the triangle and c is the third side, and is the angle between a and b .
In equation 1 , the maximum and minimum values of are 1 and -1.
so the value of c lies in between
⇒ and
=
Given a=13.2 and b=6.7 so the the side lies in between |13.2-6.7| and |13.2+6.7|
so the third side lies between 6.5 and 19.9
Answer:
4 feet
Step-by-step explanation:
We know the the area of a triangle can be represented as .
Since the height is twice the base, we can substitute the value in as
in the expression, making it
. If the area is 16, we can make the equation
Now to solve for b.
