ANSWER
a. should become narrower

88% not sure but I think so if it’s not the answer I’m sorry.
If her pratice was 1.75 hours a day, and she only did it for 8 days. You would multiple the number hours by the number of days and get 14 HOURS
SinA=BC/AB =>BC=sin75*12
cosA=AC/AB =>AC=cos75*12
the area is (1/2)AC*AB=(1/2)sin75*12*cos75*12=18
Answer:
17 : 50
Step-by-step explanation:
34 % means 34 out of 100, thus
34% = 34 : 100 ← divide both parts by 2
