Answer:

Step-by-step explanation:

So basically all you need to know for this one is that when there is an inscribed angle, the angle measure is 1/2 of the measure of the arc for that angle.

That might sound confusing, but an example from the picture is that angle ABC will be half of arc AC. This means that angle ABC is 1/2 of 120 = 60 degrees.

The answer is 60 degrees.

Sheila multiplier 62.5 by 4.08. What should have been her answer if she quickly rounded the numbers before multiplying?

kozerog [31]

The answer would be 252. Here’s why:

You always round up when it’s five (half) or above. 4 or Lower will round it down. In our question here, 62.5 would be rounded up, and 4.08 will be rounded down. This lets us rewrite the question as 63 times 4, and we get 252.

Hope this helps!
