tolong dijawab kaa trimis

1) x°+2x°+3x°=90°
6x°=90°
x°=90:6
x°= 15°
jadi 2x°= 30°
3x°=44°

2) x°+x°+x°=90°
3x°= 90°
x°= 90:3
x°=30°

3) 6x°+14x°=90°
20x°=90°
x°=90°:20°
x° =4,5°
jadi 6x°= 27°
14x°= 63°

4) 10x°+15x°+20x°=90°
45x° = 90°
x° =90°:45°
x° = 2°
jadi 10x°=20°
15x°=30°
20x°=40°

5) 2x°+2x°+5x°=90°
9x=90°
x° =90°:9°
x° = 10
jadi 2x°= 20°
5x°=50°
