The equation in standard form for the circle with radius 10 centered at the origin?

x^2 + y^2 = 100

Step-by-step explanation:

The standard form equation for a circle is:

(x – h)^2 + (y – k)^2 = r^2

Where h is the x coordinate of the center point and k is the y coordinate of the center point. Since the center point is (0,0), this simplifies to:

x^2 + y^2 = r^2

Since the radius is 10, this simplifies to:

x^2 + y^2 = 100

< 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
