If there are 45 beads, with a ratio of

Then,

Then if

Then

Therefore,

Meaning, there would be a ratio of 36 beads to 9 beads

Hello!
To find cosine, use the formula cos = adjacent / hypotenuse.
According to angle B, adjacent of angle B is side A, and the hypotenuse is side c because the hypotenuse is always opposite the right angle.
Therefore, the cosine of angle B is a/c.
U can find the unit rate by looking where is the point so in that pic the unit rate I see is: 3/5
