Express as a trinomial (3x+8) (x+10)

Step-by-step explanation:

Hello!

A trinomial is a expression consisting of three different terms

To turn this into a trinomial we multiply everything to each other

                    3x                    

3x * x =

3x * 10 = 30x

                    8                      

8 * x = 8x

8 * 10 = 80

Now we put them all together in an equation

Combine like terms

The answer is

Hope this helps!

< 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
