In the figure above, if a: b: c = 3: 4: 1, what is the value of a?

let's bear in mind that a flat-line has 180°°, therefore a + b + c = 180.

now, that total of 180 is split in a ratio of 3:4:1, what we do to get the values is simply divide the total by (3+4+1) and distribute accordingly.

the answer is c. hope this !

step-by-step explanation:

the range is 19

step-by-step explanation:

the range is biggest number minus the smallest, so in this case it would be

41 - 22 = 19
