What is the excluded value of x for the expression (x-4)^2/(x-9)^2

The excluded value of x = 9

Step-by-step explanation:

Since the Excluded values are the values that will make the denominator of a fraction equal to 0.

Because when the denominator of a rational function equals to zero it makes it infinite.

This is why we always exclude the value from the function.

Here The given expression,

Thus, for excluded value,

⇒ x - 9 = 0 ( by taking the square root on both sides)

⇒ x = 9 ( by adding 9 on both sides )

Thus, 9 is the excluded value for the given function.

< 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
