Answer:
(see below)
Step-by-step explanation:
A reflection across the y-axis is the same thing, but just mirrored on the other side. In this case, "the other side" is the y-axis.
The original rectangle was two units away from the y-axis, so this new rectangle needs to be as well.
Its area needs to also be 2 units big.
Pretty much, it's the same thing and you just place it up to a mirror.
Refer to the image below:
3 feet=1 yard
22/3=7 and 1/3
7 yards and 1/3 yard
1/3 yard=1 foot
7 yards 1 foot

Answer:
x = 50
Step-by-step explanation:
The sum of exterior angles of a convex polygon is 360°.
130° + x° + 30° + 100° + x° = 360°
2x° = 100° . . . . . . . . . subtract 260° and collect terms
x = 50 . . . . . . . . divide by 2°

<em>Additional comment</em>
If you reduce each side length to nothing, then you find the angles are measured around a central point. It becomes more clear that their sum is 360°.
