No it is not because its more then ten numbers away from the solution of the five tickets
45 × 13 = 585
Which is exactly how much he'd need to pay back his sister and buy the bike. So, it would take him 13 weeks.
45x+angle trs = 180 straight line
angle trs = 180-45x
angle trs + angle t + angle tsr = 180 (sum of angles in a triangle =180)
(180-45x) + 25x + 57+x = 180
combine like terms
180 +57 -45x+25x+x=180
237-19x=180
subtract 237 from each side
-19x =-57
divide by -19
x=3
The correct Answer should be 6
