Answer 1

a. ∠MLN = ∠KLN

= 45°

b) ∠KNL = ∠MNL

= 30°

c)∠LKM = 180° - ∠KLN - ∠LOK

= 180° - 45° - 90°

= 45°

d)∠KML = ∠LKM

= 45°

e)∠NKM = 180° - ∠KON - ∠KNL

= 180° - 90° - 30°

= 60°

f) ∠NMK = ∠NKM

= 60°

g)∠LKM + ∠KNM + ∠NML + ∠MLK

= 45° + 2(30°) + (45° + 60°) + 2(45°)

= 45° + 60° + 105° + 90°

= 300°

semoga membantu :)
