Question 621809
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 + 25 }}}
----------
{{{ a + a  - 15 + a + 25 = 180 }}}
{{{ 3a + 10 = 180 }}}
{{{ 3a = 170 }}}
{{{ a = 56.667 }}}
and
{{{ a - 15 = 41.667 }}}
{{{ a + 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 )
