Pls pls help me ASAP

1. 27.5 in.^2

2. 360 in.^2

Step-by-step explanation:

1.

A = bh/2

A = (4 + 7)(5)/2

A = 27.5 in.^2

2.

A = bh/2

A = (35 + 13)(15)/2

A = 360 in.^2

do you mean add both of the equations together

because if you do the answer is 10x-5

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
