The common rule is (x - 1, y + 3) can be used to describe the translation.
Step-by-step explanation:
Step 1:
The point J (-3, -4) becomes (-4, -1).
In order to write the rule for translation from J to , we subtract the x coordinate of J from
and subtract the y coordinate of J from
.
The x coordinate
The y coordinate
Step 2:
So from the calculations, we get that the x coordinate is subtracted by 1 i.e. and the y coordinate is increased by 3 i.e.
.
So the common rule is (x - 1, y + 3).
Answer:
Step-by-step explanation:
Let the third side of the triangle be .
We can apply the cosine rule to find .
We evaluate to obtain;
We take the positive square root of both sides to obtain;
The correct answer is B.
