When two musical notes are a “fourth” apart, the frequency of the lower note is LaTeX: \frac{3}{4}34 the frequency of the higher note. Using f as the frequency of the higher note, write an expression for the frequency of the lower note

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180

step-by-step explanation:

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
