Answer:
The answer is B.
Step-by-step explanation:
In a linear pair, the total angles is 180°. So we can form an expression for both angles. Let x be the smaller angle and 8x be the larger angle :
x + 8x = 180°
9x = 180°
x = 180° ÷ 9
x = 20°
Next, we have to substitute the x value into the larger angle expression :
8x = 8 × 20° = 160°

Answer:
1890, total cost of lights per week
Step-by-step explanation:
The lights cost 45 dollars per bulb and 6 go out per day, 45×6=270
270 is the cost to replace the bulbs of one day.
270×7=1890. 1890 is the cost for a whole weeks worth of replacing these bulbs.
