Answer:
x=10
Step-by-step explanation:
The 3 angles of a triangle add to 180
4x+60+80 = 180
Combine like terms
4x+140 =180
Subtract 140 from each side
4x+140-140=180-140
4x = 40
Divide by 4
4x/4 = 40/4
x = 10

<span>Let x be the number of hours I work. Then my earning would be 11x. For break even, earning should equal requirement. That is 11x = 160. And so, x = 160/11 = 14.55 hours/week </span>
