A. 86
B. 65
C. 130
D. 58
find the value of c

b) 65°

Step-by-step explanation:

triangles always equal 180°

from the given information, these two triangles appear to be congruent. therefore, the angle that is 29° in the left triangle should apply to the triangle on the right.

so 29° + 86° = 155

180 - 155 = 65

the missing angle is 65°

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
