Question

Finding Missing Angles in a Polygon

Answer 1

`\huge\boxed{\sf x = 130\°}`

Explanation:

Statement:

• In a quadrilateral (four sided polygon), the interior angles add up to 360 degrees.
• The angles with a small square on it represents 90 degrees.

Solution:

So,

90 + 90 + 50 + x = 360

230 + x = 360

• Subtract 230 from both sides

x = 360 - 230

x = 130°
