Answer:
d = 8 cm
Explanation:
Pre-Solving
We want to find the length of segment d.
We are given a circle, with two segments that intersect the circle. We also know that a = 4 cm, b = 12 cm, c = 6 cm.
We are also given that if two segments intersect inside or outside a circle, ab = cd. Because the two segments do intersect the circle, we can use the equation that was given.
Solving
We can plug the values that we know into the equation.
ab = cd
4 * 12 = 6 * d
Now, divide both sides by 6.
8 = d
So, d is 8 cm.
