Answer:
Triangle KLM
Step-by-step explanation:
Firstly, we need to write the coordinates of triangle NPQ
We have this as;
(-7,-6) for N
(-4,-3) for P
(-4,-6) for Q
Now, we are going to use the given translation formula;
(x + 8, y + 1)
N’ will be (-7+ 8, -6 + 1) = (1,-5)
P’ will be (-4+ 8, -3+1) = (4,-2)
Q’ will be (-4+ 8, -6+1) = (4,-5)
Now, we need to find the triangle with the exact given transformation coordinates calculated above;
We have the triangle as;
KLM
With K as (1,-5) ; L as (4,-2) and ; M as (4,-5)
Answer: 
Step-by-step explanation:
Equilateral triangle has equal sides, let the side be 
, then the perimeter is 
Therefore:
To find the altitude , we will apply Pythagoras theorem , that is
Therefore:
take the square root of both sides
The answer to the first part is 3 1/2 and the answer to the second question is 2/7
