A chord consists of notes that sound good together. The C major chord, starting at middle C, has the following frequencies
C - 262 Hz
E-330 Hz
G-392 Hz
Determine the ratio of the frequency of E to C. Express the answer in a simple integer ratio. (Due to rounding the rati
will be approximate.)
a 5 to 4
b. 3 to 2
6 to 5
d. 9 to 8

part a: triangles gcb and epb

part b. sides cg and rp are parallel by definition of parallelogram.

angles cgb and e are congruent by being alternate interior angles of parallel lines cut by a transversal. angles gbc and ebp are congruent because they are vertical angles. by aa similarity, the triangles are similar.

part c. since the triangles are similar, the ratios of the lengths of corresponding sides are equal.

calculation of be:

gb/be = cb/bp

(400 ft)/be = 300/200

(400 ft)/be = 3/2

3be = 2 * 400 ft

3be = 800 ft

be = 800/3 ft

calculation of pe:

gc/pe = cb/bp

(350 ft)/pe = 300/200

(350 ft)/pe = 3/2

3pe = 2 * 350 ft

3pe = 700 ft

pe = 700/3 ft
