Write an inequality for the given graph.

Step-by-step explanation:

Find the equation of the dashed line

The line pass through the points

-----> is the y-intercept of the line

Find the slope of the line m

The formula to calculate the slope between two points is equal to

substitute the values

Remember that

The equation of the line into slope intercept form is equal to

we have

substitute

Find the inequality

we know that

The solution of the inequality is the shaded area below the dashed line

so

< 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
