14. Rotate the triangle R(3, 1), S(1, 3), T(4, 5) 180 degrees about the origin.
A R'(1, 3), S'(3, 1), T'(5, 4)
B R'(–1, –3), S'(–3, –1), T'(–5, –4)
C R'(–3, –1), S'(–1, –3), T'(–4, –5)
D R'(3, –1), S'(1, –3), T'(4, –5)

the answer is 31.27mph

how to award brainliest:

you must wait until 2 people answer to award brainliest. i'm pretty sure that it should be next to the "" and "comments" buttons.  

step-by-step explanation:

the triangles are similar. therefore the corresponding sides are in proportion:

              cross multiply

            divide both sides by 32
