Ok so all we need to do is divide 27mph by 60 to convert the mph to miles per minute.
27/60= .45 miles per minute
Figure A best represents it because if you add 576 and 49 you get 625, which shows the theorem of a^2+b^2=c^2.
According to the Alternate Exterior Theorem, alternate exterior angles are congruent. So:
3x = 4x - 24
x = 24
But, this question is not over. This question is asking for angle RST, not x.
3(24) = 72
Hope this helped!
