What are compatible numbers for 776 divided by 28

We are given  776 divided by 28.

We need to find the compatible numbers for division of 776 by 28.

Compatiable numbers are the numbers that looks friendly and nice when doing some calculations.

For example: If we take some numbers like 10, 20, 1100, 200. It is easy to do some calculations by using those numbers.

Also note: When estimating division or other operations by using Compatiable numbers, we don't get exact values.

In the given problem we are given division operation.

First number is 776.

The compatibale number of 776 is 780 and for 28 compatible number is 30.

Because in division of 780 and 30, we can divide 78 by 3 easily and get 26. Now add one zero at the end to 26 and get 260.

< 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
