okay so we know that a circle is 360°
the one angle is 135 degrees and to find the other one we can just subtract 360 - 135
the other angle is 225°
we can set it up as:
12 yd x
——— = ——-
225 135
to find x, cross multiply 135 and 12 which gives you 1,620
1,620 / 225 = 7.2
the other angle is 7.2 yards!
