Answer 6

The sum of the interior angles of a pentagon is 540.

Answer 7

so 540/5

Answer 8

no

Answer 9

That would work for a perfect pentagon, in which all interior angles are the same measure. This is not the case. Sum up the angles you know, which are four. Subtract that from 540 and you will get x.

\[a_{1} + a_{2} + a_{3} + a_{4} + x = 540\]
