- It's very long so I'm not giving answers but here's how i would do it:
- use Pythagoras
where c is the longest side - use sine rule
where lower cases are the sides, and capitals are their opposite angles.
e.g for 15:
a = 3, b is missing, c = 10
A is missing, B is ?, C is 90

4
Step-by-step explanation:
She can use a dime and a quarter to buy one package. With 3 dimes and more than 3 quarters, she can buy 3 packages this way.
She can use 2 nickels and a quarter to buy one package. With 2 nickels and the 2 remaining quarters, she can buy 1 package this way.
Mae-Ying can buy 4 packages, and will have 1 quarter left over.
_____
You can add up her money and divide by 35¢ to find the number of packages. Doing that, you get ...
5·0.25 +3·0.10 +2·0.05 = 1.25 +0.30 +0.10 = 1.65
Then 1.65/0.35 ≈ 4.71, so Mae-Ying can buy 4 packages with the money she has.

First we have to note which number represents which axis. As a general rule x axis represents first number. It describes if figure is moving left or right.
Second number is y axis and it describes if figure is moving up or down.
Now that we said that we can see that x axis increased by 2 while y axis decreased by 1. Description that matches is:
1 square down and 2 squares right.
