A sum of money was shared among A, B and C in the ratio of 6 : 5 : 22. A and B spent $288 each while C spent $576. B then found that he had spent of 3/4 of his money. Express in the simplest ratio, the amount of money A, B and C had left.

1/4 because there is 4 grades.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
