Round 2.500 g to the nearest whole gram

3 grams

Step-by-step explanation:

Whole numbers do not include any decimals. They include numbers such as 1, 2, 3, 4, 5...

2.500 g is equal to 2 and a half grams, which we know is between 2 and 3 grams. This means that the nearest whole gram has to be 2 or 3.

When rounding, look at the digit to the right of the digit being rounded, and if it is 5 or more, round up. If it is 4 or less keep the digit same.

Here, 5 is the digit to the right of 2, so we round up to 3 grams.

< 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
