Geometry Find the value of x in each of the given figures . Need help please.

x= 80 degrees

Step-by-step explanation:

exterior angle theorem says that the exterior angle (extended line from one of sides of the triangle), 105 in this case is equal to the two opposite angles, in this case that would be 25 and x

therefore

105= 25+x

x= 80

< 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
