Question

(2.40) (9.6.2)

Answer 1

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°

Answer 2

Linear pair angles have sum 180°

$\\ \sf\longmapsto 2.4x+9.6x=180$

$\\ \sf\longmapsto 12x=180$

$\\ \sf\longmapsto x=15$

• 9.6x=9.6(15)=144°
