Answer:
- 144°
Step-by-step explanation:
The two given angles form a linear pair and therefore supplementary.
Supplementary angles sum to 180°:
- 2.4x + 9.6x = 180
- 12x = 180
- x = 180/12
- x = 15
The larger angle measure:
- 9.6*15 = 144°
Linear pair angles have sum 180°
[tex]\\ \sf\longmapsto 2.4x+9.6x=180[/tex]
[tex]\\ \sf\longmapsto 12x=180[/tex]
[tex]\\ \sf\longmapsto x=15[/tex]
- 9.6x=9.6(15)=144°
