Answer:
12
Step-by-step explanation:
So, she practices 12 hrs per week, and already has practiced 3 hrs this week.
This means she has 9 hrs left to practice.
3/4 of an hour is one session, so to find out the number of sessions she needs, you have to do (9 hours)/(one session)
which is basically 9 / ( 3/4)
She needs 12 more sessions.
Input: 0, 2, 4
Output: 3, -1, 1
0-3= -3
2-3= -1
4-3= 1
no because it is not a right angled triangle.
this means angle A is not 90° so AB cant be a tangent.
