In the following equation, which is the dependant variable? p=2l+2w

P is the dependent variable

Step-by-step explanation:

Its a formula for the perimeter of rectangle.

P represents the perimeter and l is the length and w is the width

The perimeter of rectangle depends on the length and width of the rectangle.

'l' and 'w' are the independent variables

P is the dependent variable because P depends on the length and width.

< 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
