Answer: It has no solution.

Step-by-step explanation:

3x - 12 - 4 = 3x + 4 - 4

3x - 8 = 3x

3x - 8 - 8 = 3x - 8

we can't subtract 3x-8

Doesn't add up; they need to have one solution or more for it to work.

First we will find the value of x.

To find the value of x we can add angle Q and angle O and set them equal to 180 and solve for x.

We will be setting them equal to 180 since the opposite angles of an inscribed quadrilateral are supplementary.

angle Q + angle O = 180
6x - 5 + x + 17 = 180
7x +12 = 180
7x = 168
x = 24

Now we can use 24 for x and find the value of angle QRO

angle QRO = 2x + 19
angle QRO = 2(24) + 19
angle QRO = 48 + 19
angle QRO = 67

So the answer choice B is the right answer.

Hope this helps :)

Lets do

$\\ \sf\longmapsto K=\dfrac{AB}{A+B}$
