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)

Step-by-step explanation:
Tn = a + (n - 1) d
Where
Tn is the nth term of the sequence
a is the first term of the sequence
n is the number/term of the sequence to be solved
d is the common difference
To find the area of a circle you do pi (3.14) multiplied by the radius squared.
The radius is half of the diameter: 11 / 2 = 5.5in
The radius squared is 5.5^2 = 30.25
Then take the squared radius and multiply that by pi 30.25 * 3.14 = 94.985
So the area of the circle is about 94. 99 in.

Since all three sides are different lengths and angles, that triangle would be considered an Isosceles triangle.
