If the choices are the following:
tan(22.6o) = a/13
tan(22.6o) =13/a
tan(22.6o) = a/12
tan(22.6o) = 12/a
Then the equation correctly uses the value of b to solve for a is
tan(22.6o) = a/12
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)
