Mrs. Booth is trying to building a pool with the following dimensions: 4x^2 +15
8x^2 + 10
8x^2
The following polynomial represents the perimeter of the pool, ax^2 + bx + c. Find the values of a, b, and c that represent
the perimeter of the perimeter of the pool.

No links please.

< 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

step-by-step explanation:

i have done this all on a piece of paper but idk how to put it on here cuz it needs to be drawn

other answer is correct. i had used the radius of the radius somehow. a website:
