Answer:

  • D. m∠X + m∠Y < 90°

Explanation:

Given

  • ΔXYZ with m∠Z > m∠X + m∠Y

Options

m∠X + m∠Z < 90°

  • incorrect, the sum of these two angles should be > 90°

m∠Y > 90°

  • incorrect, it should be < 90°

∠X and ∠Y are complementary

  • incorrect as angle Z is greater that the sum of angles X and Y, then sum of three angles would be greater than 180°

m∠X + m∠Y < 90°

  • correct, this is the only possible option
