Answer 1

• 12
• 7

Explanation:

Exterior angle measure is equal to the sum of non-adjacent interior angles

21..................................................

• 12x + 2 = 9x + 11 + 27
• 12x - 9x = 38 - 2
• 3x = 36
• x = 12

22..................................................

• 13x + 1 = 4x + 6 + 58
• 13x - 4x = 64 - 1
• 9x = 63
• x = 7
