Asap or 7 yrs of badluck lol find the measure of y. a. 90 b. 53 c. 43 d. 47

There's a lot of different approaches to this question, but the easiest one I see is this:

If a chord goes through the center of the circle, it is a diameter. That's 180 degrees we don't have to worry about. 47 is an inscribed angle, so we can multiply it by two to get 94 degrees. Subtract 94 from 180 to get 86.

See y? It's also an inscribed angle. To get it, we just take the 86 we just found for the remaining arc and divide by two.

The measure of y is 43.

answer: c i think

step-by-step explanation:

what are you doing do you need examples of variable questions?

step-by-step explanation:

5a-1=9               bring the one over the =

5a=10                     divide by your variable

a=2

brainliest? ?

here try this one

3a-24=0
