Answer:.
Step-by-step explanation:
The answer is the option B: A'(3, -2), B'(3, -5), C'(2, -4).
The explanation is shown below:
1. You must apply the following rule of rotation when the figure is rotated 90° counterclockwise around the origin:
→
2. Then, as you can see, you must switch
and
and multiply
by -1.
3. Keeping this on mind, you have that the vertices of the triangle A'B'C' are the following:
A(-2,-3)→A'(3,-2)
B(-5,-3)→B'(3,-5)
C(-4,-2)→C(2,-4)
4. Therefore, you can conclude that the answer is the option B.
I would have to say that it is the 3rd answer choice due to the right angle that is formed between line C and line A.
Answer:
18
Step-by-step explanation:
4(3) -(-6)
4 times 3 is 12. When you subtract a negative number the negative number gets added so it would be 12 + 6 which is 18. Hope that helps :)
