I'm honestly horrible at math, so if anyone could

B. 54 deg

Step-by-step explanation:

The sum of the measures of the angles of a triangle is 180 degrees. The triangle shown has one angle measuring 72 degrees. The other two angles have unknown measures, but they both measure y. Since the same variable y is used for both of the unknown angles, that means the two measures are equal.

We use the fact above about the sum of the measures to set up an equation.

y + y + 72 = 180

Add like terms.

2y + 72 = 180

Subtract 72 from both sides.

2y = 108

Divide both sides by 2.

y = 54

B. 54 deg

Check: 54 + 54 + 72 = 180, showing that 54 is correct.

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.
