The image of the triangle RST when rotated 90° counterclockwise around the origin is (-15,5), (-15,15) and (-5,10)

How to rotate the triangle?</h3>
The coordinates of RST are given as:
R = (5,15)
S = (15,15)
T = (10,5)
The rule of 90° counterclockwise around the origin is:
(x,y) -> (-y,x)
So, we have:
R' = (-15,5)
S' = (-15,15)
T' = (-5,10)
Hence, the image of the triangle when rotated 90° counterclockwise around the origin is (-15,5), (-15,15) and (-5,10)

Answer:
x=7
Step-by-step explanation:
first, subtract 3 on both sides:
3x=21
simplify by dividing 3 on both sides:
x=7
Answer:
D. AAA is not a congruence postulate
Step-by-step explanation:
The formula is V= l × w × h or length times width times height.
V= 45×25×60 so the answer is 67,500 but make sure you put units in your answer!
Hope this helps!
