Someone just robbed a bank. the police set a triangular perimeter of 16 kilometers where the robber may be hiding. two of the three coordinates for this triangular perimeter are (2, 2) and (-2, -1). each unit represents a kilometer. the area covered is 12 square kilometers. which of the following is the third coordinate of the triangular perimeter?

The complete question is attached here.

Option A is the third coordinate of the triangular perimeter.

Step-by-step explanation:

Given

Area=

Perimeter=

Two of the coordinates , and

We have to find the third coordinate.

From area of the triangle we can find out the height which can be used to find the stretch of the triangle as the triangle couldn't be stretched beyond its height.

So the height (h)

Finding the base using distance formula  

Base

We have assumed this length to be the base of the triangle.

Height

This gives a clue that that in coordinate plane the third points must be less than

With this option C and D are discarded,we can check it mathematically.

Now we will find the length of the triangle assigning ABC points.

Let and .

Working with the options individually.

Option A

So the perimeter

Hence is the third coordinate of the triangle.

step-by-step explanation:

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
