Answer 1

Answer:

Sum of interior angles of a quadrilateral is 360°

• 110° + 130° + x + x - 3° = 360°
• 2x = 360° - 237°
• 2x = 123°
• x = 61.5°

(18)

Sum of interior angles of a hexagon is 180°*(6 - 2) = 720°

• 2*90° + 2x + 2(x + 22°) = 720°
• 90° + x + x + 22° = 360°
• 2x = 360° - 112°
• 2x = 248°
• x = 124°

Interior angles of a given pentagon are all marked as congruent, so the exterior angles are congruent too.

Sum of exterior angles is 360°.

• x = 360°/5
• x = 72°
