What is the best estimate of the measure of the angle shown?

65

Step-by-step explanation:

We know it is less than a right angle or 90 degrees It is bigger than 1/2 of a right angle or bigger than 45 degrees

The best estimate is 65 degrees

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.

the answer should be a. snail
