Answer:

x = 8

Step-by-step explanation:

Using the sine or cosine ratio in the right triangle and the exact value

A short necklace has 32 gold beads and 8 black beads.
joja [24]

Answer:

12 black beads

Step-by-step explanation:

Given the ration of gold beads to black beads on the short necklace:

\frac{gold}{black}=\frac{32}{8}=\frac{4}{1}

Since the ratio of 4:1 has 5 total parts, you can take the total amount of beads in the long necklace and divide by 5:

60 ÷ 5 = 12

12 beads represents 1 part of the ratio, so that would be the number of black beads.  To check, multiply 12 by 4:  12 x 4 = 48, and set up a ratio:

48: 12 = 4: 1
