Question 230347
<font face="Garamond" size="+2">


The sum of the measures of the interior angles of any triangle is 180°.  The base angles of an isosceles triangle are equal in measure. Let *[tex \Large x] represent the measure of one of the base angles.  Then, given that the obtuse angle measures 120°, we can say:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ x\ +\ x\ +\ 120\ =\ 180]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 2x\ +\ 120\ =\ 180]


Solve for *[tex \Large x].
