What is 443,219 rounded to the nearest ten thousand

Okay, so we have the number 443,219. And we need to round to the nearest ten thousand.

443,219

The bolded number shows the ten thousands place. Now we need to know whether we round down, or round up. To decide which one to do, we need to look at the number in the thousandths place. The rule is...

If the number is 4 or less, then we round down. If the number is 5 or more then we round up.

In the number 443,219 the 3 is the number in the thousandths place.

Since 3 falls into the category of '4 or less', we know that we need to round down. So 443,219 becomes 440,000

step-by-step explanation:

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
