The frequency of the musical note E3 is about 164.81 Hz.
laiz [17]
A perfect fifth above a note has a frequency ratio of 3 to 2.
Therefore, we can set the proportion:
164.81 : x = 2 : 3

which gives:
x = <span>164.81 </span>× 3 ÷ 2
   = 247.21

Hence, the perfect fifth above E₃ will have a frequency of 247.21Hz which corresponds to a B₃.

SAM ≅ ΔZYX , <br> Options:<br> M = 36<br><br> M = 60<br><br> M = 84<br><br> M = 102
Reil [10]

Answer:

<u>M = 36</u>

Step-by-step explanation:

Since SAM = ZYX

We can assume that all angles on SAM will equal the same as ZYX.

There are 180° total in a triangle, so you add 60 + 84, which equals 144, then you subtract 144 from 180 to find the remaining angle.

Therefore M = 36°
