Student A is wrong and Student B is correct.

How?

Direction is saying to construct a line that passes through C
The last step is enough to describe that A is wrong.
Its saying to swing an arc(Should be line).
On the other hand Student B has done correct
By passing point through C and G it satisfies our required construction.

7.9

Step-by-step explanation:

She has a total of 51.2 and uses 12.9+30.4.

The equation would be 51.2-(12.9+30.4).

51.2-(12.9+30.4)

=51.2-43.3

=7.9
