Answer:
x = 15
Step-by-step explanation:
Assuming you require the value of x
The product of the external part and the whole of one secant is equal to the external part and the whole of the other secant, that is
9(9 + x) = 8(8 + 19), that is
81 + 9x = 8 × 27 = 216 ( subtract 81 from both sides )
9x = 135 ( divide both sides by 9 )
x = 15
