To turn 2/5 into a decimal, what operation
must you perform?
a. 2÷5
b. 2x5
c.5-2
d. 5÷2

A

Step-by-step explanation:

I learned by being told Ned and the donkey. Ned is the Numerator and the donkey is the denominator. Ned goes inside and the donkey goes outside. So the numerator goes first when you divide in this case 2. And the Denominator goes last in this case 5. So it is 2 divided by 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
