Answer 1

Answer:

• 84°
• 125°

Step-by-step explanation:

Sum of the interior angles of a regular polygon:

• S(n) = 180°(n - 2), where n- number of sides

Exercise 4

Pentagon has sum of angles:

• S(5) = 180°(5 - 2) = 540°

Sum the given angles and find x:

• x° + 122° + 100° + 90° + 144° = 540°
• x° + 456° = 540°
• x° = 540° - 456°
• x° = 84°

Exercise 5

Hexagon has sum of angles:

• S(6) = 180°(6 - 2) = 720°

Sum the given angles and find x:

• x° + 110° + 160° + 105° + 105° + 115° = 720°
• x° + 595° = 720°
• x° = 720° - 595°
• x° = 125°
