Yg aku buletin ada yg tau gk yh?#tolongbantujawab

Answer 1

4.Sudut ACD = Sudut ABC + Sudut BAC
=55°+65°
=120°

6.Sudut Q + Sudut R = 180°
<=>4x°+x°+70°=180°
<=>5x°+70°=180°
<=>5x°=110°
<=>x=110\5
<=>x=22

Sudut R = x°+70°
=22°+70°
=92°

Answer 2

3. 4x+5x+6x=180°
15x=180°
x=180:15=12
6x=6(12)=72°

4. Sudut ACB=180-120
=60°
Sudut ACD=180-60
=120°

6. 250+5x=360
5x=360-250
=110
x=110:5=22°
Sudut R = x+70°
=22+70
=92°
