Given the figure below, find the value of x and z.

z = 109 x = 12

Step-by-step explanation:

Well z is is very simple it is 109 because 109 and a are opposite from each other so they are the same.

But to find x some math is needed.

We know that 109 and (8x-25) are summplementary angles meaning they add up to 180.

So we can set up the following equation

So we have to combine like terms meaning adding -25 and 109 which is 84.

And we also have to put the whole numbers on one side so we so 180-84 which is 96.

Now our equation looks like this -> .

And to get x by itself we do 96÷8 which is 12.

So x is 12.

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
