B, You have to break it down and you'll get your answer
D) Rotate 180° about the origin
Well.....is it a sin to say Madison beer?
Angle TRS is equal to 180 - 9x (straight angles).
The sum of all the interior angles of a triangle is 180. Thus,
180 - 9x + 5x + 9 + x = 180, resulting in -9x + 5x + 9 + x = 0.
Then -4x + x = -9, or -3x = -9, or x = 3 (answer)
