X + 5
X + 1
O 12

x = 12

Step-by-step explanation:

Looking at the diagram, we can deduct that the appropriate formula to use is form power of a point, specifically when two secants intersect outside of a circle. Using this, you get the equation:

(x + 5 + 7)(7) = (x + 1 + 8)(8)

And, you can simplify and solve:

(x + 12)(7) = (x + 9)(8)

7x + 84 = 8x + 72

84 = x + 72

x = 12

good job you smart son of a gun you are smarter that einstein. 7
