In the diagram below, EF intersects AB and CD at G and H, respectively. GI is drawn such that GH ≅ IH. If m∡EGB = 50 and m∡DIG = 115, explain why AB ∥ CD.

< 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

understand that i don't know the answers

will someone answer his question

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
