What value of x makes this true? x/-7=-4.

28

Step-by-step explanation:

-4+-7=28 you just reverse the division problem

x/-7=-4

to get rid of -7, multiply -7 on both sides of the equation

(-7)x/-7=-4(-7)

x=28

on your paper it doesn't say the answer but the the answer is altitude

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
