Ответ:
Each can of juice costs 35 cents.
We want to find out how many cans of juice she bought.
Rosa gave the cashier 10 quarters so she has 5 quarters left.
10 quarters equals to about $2.50
Rosa gave the cashier 6 nickels, so she has 4 nickels left.
6 nicks equals 30 cents.
Let's add up the total amount of money Rosa paid the cashier.
$2.50 (quarters) + $0.30 (nickels) = $2.80 (total paid to the cashier)
Now, we know each drink is $0.35, and Rosa paid $2.80 to the cashier.
Simply divide $2.80 by $0.35
$2.80 (total amount paid) ÷ $0.35 (per can) = 8 (cans)
Rosa bought 8 cans.
Also, if you need to know how much money Rosa has left:
5 quarters left = $1.25
4 nickels left = $0.20
Rosa has a total of $1.45 left - just enough for 4 more cans of soda.

61 degrees
Step-by-step explanation:
Since we know there is a 90 degree angle and a 29 degree angle..
90 + 29 + a = 180
119 + a = 180
a = 61 degrees
