Question

Tolong d jawab y no.1

Answer 1

MLN = KLO = 65° 
LKO = NKO = 35°

NKL = 35 + 35 = 70
MLK = 65 + 65 = 130 

130 + 70 = 200
360-200 = 160
160 ÷ 2 = 80°

Answer 2

Karena segitiga sama kaki maka sudut kaki nya sama.

sudut KNL = sudut KLN
sudut MNL = sudut MLN

sudut LKN
= 180 - ( 90 + 35 )
= 180 - 125
= 55

sudut KNO
= 55

sudut MNL
= 65

sudut NML
= 180 - ( 65 + 65 )
= 180 - 130
= 50
