Which transformations should be applied first
1. vertical stretch by a factor of 3
2. reflection over the y-axis
3. horizontal shift left 2 units
4. vertical shift down 6 units

answer: suck one

step-by-step explanation: suck one

a negative exponent is translated as follows:

so, we have

< 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
