Find a number that both of the denominates make the same number for example if one denominator is 1/7 and the other is 2/6 then you

2/6 * 7 = 14 over 42 then the other one would be 1/7 *6 which would be 6 over 42 you find common denominators by finding a number both of the bottom ones can equal. hope this helps

What is the value of y ?
Dmitry [639]

Answer:

6

Step-by-step explanation:

Chords within a circle are proportional. Proportional means that they form equal ratios. To solve for y, set up a proportion.

The ratios we will create will be \frac{long}{short} =\frac{long}{short} where each long and short form an angle.

So write:

\frac{12}{8} =\frac{y}{4}

To solve, cross multiply numerator with denominator.

12(4) = 8(y)

48=8y

6=y

klio [65]
I think i am doing this right i am not sure. First you need to add up all the sides (100+38+22+15) it would equal 175 then you need to subtract it from 360 and get the missing value (x) then the answer would be 185
