Answer:
Step-by-step explanation:
A - C = ( -2, 9) - (- 2 -3)
= ( 0, 12)
AC = 12
B - C = (7 - 3) - ( - 2 -3)
= (9, 0)
BC = 9
ABC is a right -angled triangle with AC as the hypotenuse
AC = sqrt( 9^2 + 12^2)
= sqrt(81 + 144)
= srqt(225)
= 15
Perimeter = 12 + 9 + 15
= 36 units
So the answer is 36 units
Answer: -12

Answer: 15 pongs you say?
Step-by-step explanation:
Mapping the triangle on one another simply means you use rigid transformations, which involve scaling. So the second triangle is congruent.
Since 3 is the shortest side, 27 pairs with three, so:
27/3 = 9
The second triangle is 9 times larger.
Using this we can do:
5 * 9 = 45
6 * 9 = 54
since 6 is the largest side, 54 is our answer! Or is it?
Note that this is a right triangle, so we use the Pythagorean theorem to find the hypotenuse.
= 
so 9*sqrt(34) is our answer
The repeating decimal .99999 is equal to 1.
This can be proven by doing the following math
