What is the value of x? These are the options!
1- x= 15
2- x= 12
3- x= 24
4- x= 17

since they are vertically opposite angles(equal)

4x-10=58

4x=68

x=17

option 4

Step-by-step explanation:

(4x - 10) and 58 are alternate angles and are congruent, then

4x - 10 = 58 ( add 10 to both sides )

4x = 68 ( divide both sides by 4 )

x = 17

11 feet 6 inches and 8 feet 6 inches

< 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
