The image of the triangle RST when rotated 90° counterclockwise around the origin is (-15,5), (-15,15) and (-5,10)
<h3>
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)

It’s already in standard form
Answer:
distance around the triangle refers to the perimeter of that equilateral triangle so 35 + 35 + 35 = 105cm
Answer:
I think it is 40.5
Step-by-step explanation:
If each 1cm cube is 12 grams, I figure the other cubes would be proportional and a 1.5cm cube comes up to be 3.375cm^3, not 1 cm^3, thus we multiply the rate to 3.375 to get 40.5 as the mass of the 1.5 cm cube
