Answer:
x = 40
Step-by-step explanation:
Given 2 secants from an external point to the circle, then
The product of the external part and the whole of one secant is equal to the product of the external part and the whole of the other secant, that is
8(8 + x) = 12(12 + 20)
8(8 + x) = 12 × 32 = 384 ( divide both sides by 8 )
8 + x = 48 ( subtract 8 from both sides )
x = 40
65 is the answer,I just put it into a calculator,but all that really is is multiplying,a negative times a negative equals a positive so you would take -6.5×2=-13
-13×-5=65
