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.

x = central angle apc = measure of minor arc ac

the two angles x and 30 add to 180, so x+30 = 180 and x = 180-30 = 150. the measure of minor arc ac is 150 degrees.

what we need to do from here is find the circumference and then multiply it by x/360 since there are 360 degrees in a circle. in this case, x = 150, so x/360 = 150/360 = 15/36 = 5/12. the shortest distance along the curve from a to c is 5/12 of the distance around the entire circle (aka circumference)

c = circumference

c = pi*d

c = pi*24

c = 24pi

now multiply this by 5/12 to get

distance along minor arc ac = (5/12)*(circumference)

distance along minor arc ac = (5/12)*(24pi)

distance along minor arc ac = 10pi

the formula you can use is

l = (x/360)*pi*d

with

l = length of minor arc

x = central angle

d = diameter

which essentially is the steps we took though a bit differently.
