I think its 32 I'm not sure
A, 1/2*b*h*sin
A, 1/2*12*8*sin 62
=43.3
Also use symbolab for this kid equations
Step-by-step explanation:
f
step-by-step explanation:
< 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
