Question

bantu jawab donk kak​

Answer 1

Jawaban:

[Sudut]

Penjelasan dengan langkah-langkah:

< pelurus = 180° ( Berjumlah 180° )

< bertolakbekang = sama besar sudutnya

a = 50° = < c

b = 130° = bertolak belakang < 130°

c = 50° = < a

d = 100° = < f

e = 80°= bertolak belakang < 80°

f = 100° = < d

g = 60° = < i

h = 120° = bertolak belskang < 120°

i = 60° = < g

j = 65° = < l

k = 115° = bertolak belakang 115°

l = 65° = < j
