Hey, this this problem eight. And we need to find the measure of Arc D e e. What we know is we know that the arc length of Arc de E is equal to 8.73 inches. We know that the radius is 10 inches, and we know that we have a formula that says the Ark Link uh D E e will be equal to the measure of Arc de over 360 degrees times two pi r. So knowing that we have the information that we have, we can substitute in this information. So the arc length of D E is 8.73 inches. We don't know the measure of d E the Art D. That's what we're trying to find. No. And we know that our radius is 10. So now we can go ahead and start solving this. We can multiply both sides by 360. So we're gonna have 8 73 times 3 60 and we can divide both sides by 20 pie. And that is gonna leave us with the measure of Arc de e. So when we calculate this out, turns out it's going to be 50.2 degrees equals the measure of Arc de e
