Which of the following graphs shows the solution to the system of equations?

< 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

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative

the answer is 18 units because there are 18 small cubes inside the rectangle

hope this and p.s i am also in k12
