To prove:

∠ACB ≅ ∠DEB

             Statements                                 Reasons

Rosa is building a guitar. The second fret is 33.641\,\text{mm}33.641mm from the first fret. The third fret is 31.749\,\text{mm}
yulyashka [42]

Answer:

65.39 mm.

Step-by-step explanation:

We have been given that Rosa is building a guitar. The second fret is 33.641 mm from the first fret. The third fret is 31.749 mm from the second fret.

We can find the distance between third fret and first fret by adding the distances between first fret to second fret and second fret to third fret.

\text{Distance between 1st fret and 3rd fret}=33.641+ 31.749

\text{Distance between 1st fret and 3rd fret}=65.39

Therefore, 3rd fret is 65.39 mm away from 1st fret.
