Help me out with this math

104

Step-by-step explanation:

Using angle rules, we know that angle 6 and angle 4 are congruent. Since angle 4 and angle 3 are on the same line, we can find angle 3 by subtracting 76 from 180 which is 104. Angle 1 and angle 5 are opposite each other so they are congruent.

Angle 1 and Angle 3 both equal to 104 degrees.

answer: x= -2y

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
