The answer is c(4) because if you multiply 4 three times it equals 64
The perimeter of triangle is: 14.15 units
Step-by-step explanation:
First of all we have to find the lengths of sides of triangles
Given
A(3, 1), B(2, -1), and C(-3, 2)
The distance formula will be used to find the lengths of sides
So,
The perimeter of triangle will be:
Hence,
The perimeter of triangle is: 14.15 units

Answer:
The length of legs lm, mn, and lk is 32 while that of kn is 36.
Step-by-step explanation:
The diagram is attached in the answer.
As both the angles are equal thus the two forms isosceles triangles. This is true because the converse of base angle theorem is applicable here. The theorem clearly states that when a trapezoid is divided by the diagonal, it forms two set of angles where m<1=m<2 and m<lmk=m<nmk
This leads the two set of legs such as
Or this could be written as
Now the remaining two sides are given as
as this form an isosceles triangle so
Similarly
Or
Now the perimeter is given as
Here perimeter is given as 132 so this gives:
So the four legs are of length as given below:
So the length of legs lm, mn, and lk is 32 while that of kn is 36.
