Answer 2

Answer:

1) ∠a = 108°

2) ∠b = 120°

3) ∠c = 90°

4) 318° or 360° (including x)

5) x = 42°

Answers with detailed explanation:

1) ∠a = 108° (The regular pentagon has each interior angle is 108°)

2) ∠b = 120° (The regular hexagon has each interior angle is 120°)

3) ∠c = 90° (The square has each interior angle is 90°)

4) 108° + 120° + 90° = 318°

5) 108° + 120° + 90° + x = 360° (Angle sum property of a polygon)

= 318° + x = 360°

= x = 360° - 318°

= x = 42°

Hope it helps you!
