Answer 1

look at the picture above

Answer 2

x = 134°

Explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 7, thus

sum = 180° × 5 = 900°

Sum the interior angles and equate to 900

x + 126 + 128 + 132 + 123 + 132 + 125 = 900, that is

x + 766 = 900 ( subtract 766 from both sides )

x = 134°
