Television $350.
I discount price $300.

change 50 discount

Given:

Original of television = $350

Discount price = $300

To find:

Percent of discount

Solution:

Discount amount = Original price - Discount price

                             = $350 - $300

Discount amount = $50

                             = 14.28%

Percentage of discount is 14.28%.

< 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
