Arah: Selesaikan x dan tentukan besar sudut-sudut berikut.
Besar x
→ 4x + 2x = 180°
→ 6x = 180°
→ x = 30°
1.) [tex] \angle a [/tex]
→ 2x
→ 2(30°)
→ 60°
2.) [tex] \angle h[/tex]
→ 2x
→ 2(30°)
→ 60°
3.) [tex] \angle e [/tex]
→ 4x
→ 4(30°)
→ 120°
4.) [tex] \angle f [/tex]
→ 2x
→ 2(30°)
→ 60°
5.) [tex] \angle d [/tex]
→ 4x
→ 4(30°)
→ 120°
