Answer:

  • 65°, 120°, 55°, 30°, 36°

Step-by-step explanation:

Q1

  • 2x + 50° = 180°
  • 2x = 130°
  • x = 65°

Q2

x is the sum of supplementary angles of 125° and 115°

  • x = 180° - 125° + 180° - 115° = 55° + 65° = 120°

Q3

  • x = 25° + (45° - 15°) = 25° + 30° = 55°

Q4

  • (180° - 60°) - 3x = 90° - 2x
  • 120° - 90° = 3x - 2x
  • x = 30°

Q5

  • 2x + 3x = 180°
  • 5x = 180°
  • x = 36°
