9. Example of Exam
I n the kite KLMN, we know angle
ONM = 25°, angle KLO = 30°.
Then angle LMN = … N
K MO
L

10. Answer :
1.180 - (ONM+NOM) = NMO
180 - ( 25 + 90 ) = NMO
180 - 115 = 65°
2. KLO = MLO = 30°
3. 180 - (MLO+LOM) = OML
180 - ( 30 + 90 ) = OML
180 - 120 = 60°
4. Angle LMN = NMO + OML
LMN = 65 + 60
LMN = 125°
N
