On a boat, a cabin's window is in the shape of an isosceles trapezoid, as shown below. What is the area of the window?

140 square inches

150 square inches

195 square inches

390 square inches

195

Step-by-step explanation:

½(B¹ + B²) h is the formula for a trapezoid so you would do

1/2(10+16)15 which gives you 195

< 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
