Step-by-step explanation:
An arc of a circle is a "portion" of the circumference of the circle. The length of an arc is simply the length of its "portion" of the circumference. The circumference itself can be considered a full circle arc length. ... the angle subtends, s, divided by the radius of the circle, r.
Since 7y and 5y has the same variable, add them together.
7y + 5y = 12y
We get 12y, so y has to multiply 12 to get 16. I divided 16 by 12, which got me 1.3333333.
16 divide by 12 = 1.33333333
y = 1.33333333 ( 3 keeps going on )
