The first two terms of an arithmetic progression are shown. р 5p

The sum of the first three terms is 90
Work out the value of p.

< 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

#15. square

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72

answer: 12x^2+6x

step-by-step explanation:

6x does not equal 24x. hope it works!
