Question

I need help finding x for this problem (Angles of Polygons, image attached below).

Answer 1

add all the sides together

98 + 143 + 101 + 125 + 147 = x

simplify

614 = x

Answer 2

6 sided shape has 720 degrees for interior angles.
Add 143 + 98 + 125 + 101 + 147 = 614.
720 - 614 = x
x = 106.
