The point G(5, - 9) is rotated 90° about point M(-8, 3) and then reflected across the line y = 9. Find the coordinates of the image G'.

8

step-by-step explanation:

this is a subtraction problem.

10 - 2 = 8

< 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
