Let +a+ = the angle at the steering column
given:
The angle where the seat support meets the crossbar is
+a+-+15+
The angle at the peddle gear is
+a+%2B+25+
----------
+a+%2B+a++-+15+%2B+a+%2B+25+=+180+
+3a+%2B+10+=+180+
+3a+=+170+
+a+=+56.667+
and
+a+-+15+=+41.667+
+a+%2B+25+=+81.667+
The 3 angles are 56 2/3, 41 2/3, and 81 2/3
check answer:
56 2/3 + 41 2/3 + 81 2/3 = 56 + 41 + 81 + 6/3
= 178 + 2
= 180 degrees
OK
( ps- angels are the baseball team or the ones with wings )

It's pedal, not peddle.
