Write the explicit equation for the arithmetic sequence where the first term is 1 and the third term is 6.

< 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

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23

answer is 33

step-by-step explanation:

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
