Answer: 10
Step-by-step explanation:
By the alternate interior angles theorem,

Let
x = # of <span>$5 dollar bills
y = </span># of <span>$10 dollar bills
x + y = 12 so x = 12 - y
5x + 10y = 95
substitute </span>x = 12 - y into 5x + 10y = 95
5x + 10y = 95
5(12 - y) + 10y = 95
60 - 5y + 10y = 95
5y = 35
y = 7
x = 12 - 7 = 5
answer
# of <span>$5 dollar bills = 5
</span># of $10 dollar bills = 7
The first one is 37 and the second one is 49
Answer: 63°
<u>Step-by-step explanation:</u>
Since BD is the diameter, then arc BCD = 180°
Given that arc BC = 54°, then arc CD = 180° - 54° = 126°
∠DBC is an intercepted angle -> DBC = half of arc CD
