Answer:

Right - 90°

Step-by-step explanation:

  • Acute angle => less than 90°
  • Right angle => exactly 90°
  • Obtuse angle => more than 90° less than 180°
  • Straight angle =>exactly 180°
  • Reflex angle => more than 180° , less than 360°
  • Full angle => exactly 360°

∠ABD = 40°

∠DBC = 50°

∠ABC = 40° + 50° = 90° So, ∠ABC is a Right angle and formed with measure 90°
