We have
angle 1=
see the attached picture to better understand the problem
we know that
<span>Vertical angles are congruent
</span>
<span>
and
adjacent angles are supplementary
</span>
<span>
if the measure of one of the angles is </span>
degrees and straight lines equal 
<span> degrees you have to
subtract </span> from
so
therefore
the answer is
the measures of the other three angles are
