Answer: The Speed of The Ball (I think....)
<u>Answer</u>
2
<u>Explanation</u>
The two lines in the diagram are secants meeting outside the circle.
The products of a secant and the extension of the chord of one line is equal to the products of a secant and the extension of the chord of the other line.
∴ 3(3+5) = 4(4+x)
3 × 8 = (4×4)+(4×x)
24 = 16 + 4x
4x = 24 - 16
4x = 8
x = 8/4
= 2
It’s b beacuse you have to Dvide by 2
