Answer:
1. <BAC
2. <DAF, <FAE, <FAB, <FAC
3. 4 angles, <DAF, <FAE
Step-by-step explanation:
1. since A is the vertex, A should be placed in the center of B and C regardless of which letter is written first
2. A is the only vertex; therefore, write all angles possible and retain only those with point F
3. an acute angle is any angle less than 90°
