An equation is shown.
2x2 - x - 6 = 0
what is one solution to the equation?

Step-by-step explanation:

Given the following Quadratic equation:

You can use the Quadratic formula in order to solve it.

The Quadratic formula is:

In this case you can identify that:

Therefore, knowing these values, you can substitute them into the Quadratic formula.

Then, you get:

< 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
