Through a point, not a given line, how many perpendicular lines can be drawn to the given line? a. two b. infinite c. none d. only one

D. Only one

Step-by-step explanation:

Lines are perpendicular if they intersect to form a right angle (90°).

The perpendicular postulate tells you that when you have a line and a point not on the line, then there is only one perpendicular line that can be drawn through the point to the line.

< 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
