Give 5 rational number equivalent to 59

Step-by-step explanation:

−5 It can be written 9−5 = 9×2−5×2 = 18−10  9−5 = 9×3−5×3 = 27

−159−5 =

9×4

−5×4

=

36

−20

Therefore,  

18

−10

,

27

−15

 and  

36

−20

 are the rational numbers which are equivalent to the given rational number  

9

−5

.

< 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
