What is the length of CD¯¯¯¯¯¯¯¯?
vladimir2022 [97]

Answer:

23 units

Step-by-step explanation:

Since both lines are chords, they're equal in length. This means we can set them equal to each other.

2x + 2x +2 = 15 + 8

This becomes 4x + 2 = 23.

Subtract two from each side to get 4x = 21.

Now divide by 4 to isolate x.

This makes x = 5.25.

Now we take the 5.25 and substitute it into the 2x + 2x + 2. This equals 23 units
