Answer:
The correct Options are : C; {3, 4.5, 5}
Step-by-step explanation:
3a + 4 ≥ 13
Subtracting 4 from both the sides
⇒ 3a + 4 - 4 ≥ 13 - 4
⇒ 3a ≥ 9
Dividing by 3 both the sides
⇒ a ≥ 3
Therefore, The numbers from the set are : 3 , 4.5 , 5
Thus, The correct Options are : C; {3, 4.5, 5}
sin A=opposite/hypotenuse
=12/15
=4/5
cos A = adjacent/hypotenuse
=9/15
=3/5
tan A =opposite/adjacent
=12/9
=4/3
