answer letter c. answer only no explanation

Consider kite KLMN on the right. 1. Name the pairs of congruent and adjacent sides. 2. If LM = 6, what is MN? 3. If LN = 7 cm and KM = 13 cm, what is KL? 4. If KL = 7 cm, what is KM? 5. If the area is 96 cm² and LN = 8 cm, what is the area? 6. If m∠K = 63°, what is m∠3? 7. If m∠L = 31°, what is m∠MN? 8. If m∠5 = 22°, what is m∠4? 9. If m∠KL = 39°, what is m∠MN?

Solution

  1. Pairs of congruent sides: KL = MN, KN = LM.
  2. LM = 6, MN = 5.
  3. LN = 7 cm, KN = 13 cm.
  4. KL = 13 cm, KM = 5 cm.
  5. Area = 96 cm².
  6. m∠K = 63°.
  7. m∠L = 31°.
  8. m∠M = 22°.
  9. m∠K = 39°, m∠L = 41°.
  10. m∠L = 70°, m∠K = 40°.
