Step-by-step explanation:

To find: factors of the composite number

Solution:

Numbers that have exactly two factors are known as prime numbers.

Composite numbers are numbers which have at least 3 factors.

For example,

consider a composite number 54

×

Here, 54 is a composite number as it has factors 1, 54, 2, 27, 3, 18, 6, 9.

In the factorisation ×, 3 and 2 are prime numbers.

18a

step-by-step explanation:

simply because it is. it's the highest common factor

< 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
