Answer:
x=12
Step-by-step explanation:
What we have here is a secant and tangent. Using this theorem,
Given the segments of a secant segment and a tangent segment which share an endpoint outside of a circle,
The product lengths of the secant segment and external secant segment equals the length of the tangent segment squared.
In other words,




tan(70)=12cm/y The tangent of the angle equals the opposite over the adjacent
y=12cm/tan(70) Isolate y and plug into calculator
y = 4.4 cm (Rounded to the nearest tenth)
