Help me please.

x=70 degrees

Step-by-step explanation:

These angles are what we call alternate interior angles. They are equal. So we can make the equation:

x+55=2x-15

Add 15 to both sides and subtract x from both sides

70=x

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
