AOC = x°, BOC =y°

(1)Karena itu garis lurus, maka besar sudutnya adalah 180°

a). Sudut AOC = 105°, maka BOC?

180°= x°+ y°

y° = 180° – 105°

y° / BOC = 75°

b). Sudut BOC = 82°, maka AOC?

180° = x° + y°

x° = 180° – 82°

x° = 98°

(2)

a). tent. nilai a dan b

180° = a° + a° + 68°

2a = 180° – 68°

2a = 112°

a = 56°

180° = 2b + 5b + 12

7b= 180° – 12°

7b = 168°

b = 24°

b)Besar sudut DEG dan KLN

Sudut DEG = 68° + 56°

= 124°

Sudut KLN = (5b + 12)

= 5(24°) + 12

= 132°

Semoga membantu..

1a.besar sudut BOC=180°-105°

=75°

b.besar sudutAOC=180°-82°

=98°

2a.68°+a°+a°=180°

68°+2a° =180°

2a° =180°- 68°

2a° =112°

a° =112°/2

a° =56°

5b°+12°+2b°= 180°

7b°+12° = 180°

7b° =180°-12°

7b° =168°

b° =168°/7

b° =24

b.besar sudut DEG=a°+68°

=56°+68°

=124°

besar sudut KLN =5b° + 12°

=(5xb)+12°

=(5×24)+12°

=120°+12°

=132°

maaf kalau salah
