Answer:
DC = 3
Step-by-step explanation:
Based on triangle similarity theorem, we would have the following equation:

Plug in the values



Cross multiply
3(9 + DC) = 9×4
27 + 3DC = 36
Subtract 27 from each side
3DC = 36 - 27
3DC = 9
Divide both sides by 3
DC = 9/3
DC = 3
Answer:
D. -2
Step-by-step explanation:
The zero of a function is always along the x-axis and in this case that's -2.
Hope this helps :)
Answer:
9°
Step-by-step explanation:
In a ∆, equal sides make equal angle to the third side. So the angle that's not mentioned is same '2'.
Sum of angles in a ∆ = 180°
80° + m/_2 + m/_2 = 180°
80° + (5x + 5) + (5x + 5) = 180°
10x + 90° = 180°
10x = 90°
x = 9°
Answer: The value of d 62 + 5
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.


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