Numbers 100 to 125 are written on separate slips (one number on one slip), kept in a box and mixed well. One slip is chosen from the box without looking in to it. What is the probability of getting a number 108?

1/25

Step-by-step explanation:

In 100 to 125, the difference is 25.

so, there is only 1 possibility of there being 108 from 100 to 125 so its 1/25

< 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

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
