I'll legit cry if you can show me a step by step on how to solve this... pls oh my god

Answer:
x=4
ab=51
ac=51
Step-by-step explanation:
Call the point at the centre of the circle 'X'
1) Draw two lines from X, one joining B and one joining C. Each line is a radius.
2)Draw a line from A to X.
3) We now have two triangles: ΔABX and ΔACX.
4) We know that these triangles are congruent as we can say with certain they share two of the same side lengths (BX=CX because they're both the radius, and AX is common to both triangles).
4)Knowing that they're congruent, we can say that AB=AC:
AB=AC
14x-5=3+12x
14x-12x=3+5
2x = 8
x = 4
Therefore AB=14(4)-5=51
AC=3+12(4)=51

So to solve for x, you'll need to combine all the angles and equal it to 720, and from there we can solve.
Combine like terms to get
Subtract 470 on each side to get
Then just divide on each side and you'll get
To find the value of the (x+10) angle, just substitute 125 for x and solve.

The missing value x=3 is obtained by the concept of slope in coordinate geometry.
<h3>What is slope?</h3>Positive or negative rates of change are both possible. Since the slope of a line is determined by the ratio of the vertical and horizontal change between any two locations on a plane or line, the slope is determined by the rise to run ratio. Where, Rise is the difference in elevation between two points. The horizontal shift between two places is known as a run.
Formula of slope = (equation 1)
According to the question the coordinates are: xi=2, x2=x, y1=6, y2=10
Given, rate of change=4 (here rate of change=slope)
Putting all coordinates in equation 1
Slope=
4=4/x-2
x-2=1
x=3
Therefore, the missing value x=3
