What would be the equation containing the points (-8,-,,15)

Step-by-step explanation:

step 1

Find the slope

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

take the points

(-8,-15),(-3,0)

substitute in the formula

step 2

Find the equation in point slope form

we have

substitute

step 3

Convert to slope intercept form

apply distributive property right side

< 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
