Problem 1
Use the theorem for the product of chord segments to find the value of $$ x $$.
Use the formula and substitute the values:
$ \red x \cdot 1 = 2 \cdot 4 \\ \red x = 8 $
Problem 23
In the circle below, the chord segments have the following lengths: A = 6, C = 3, D = 4. Use the theorem for the product of chord segments to find the value of D.
Problem 3
In the circle below, the chord segments have the following lengths: D = 8, C = 3, A = 6. Use the theorem for the product of chord segments to find the value of B.
A • B = C • D
A • B = 3 • 8
6 • B = 24
B = 24 ÷ 6
B = 4
