I'm not sure how to find angle 5 and 6

angle 5 = 17 degrees

angle 6 = 129 degrees

Step-by-step explanation:

Start by finding angle 5 by doing 90+39+x+34=180

You get 17 degrees for angle 5

Then, find angle 6 by doing 17+34+x=180, which is 129 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 is (-4,-4)

hope this ! : d
