Question

Find the length of chord EF.

Answer 1

EF = 26 units.

Explanation:

The arcs CD and EF are equal so the chords CD and EF are also equal. So:

9x - 1 = 41 - 5x

9x + 5x = 41 + 1

14x = 42

x = 3.

Therefore EF = 41 - 5(3)

= 26 units.

Answer 2

The answer is 26. I added an image that has the explanation for the problem.
