Answer:
C. 12,24,24
Step-by-step explanation:
12 is already there and there must be one more 12.
72-24=48
48÷2=24
=12,24,24
f(x)=x² +3x-x/2
f(6)=(6)²+3(6)-6/2
= 36 + 18 -3
=51
20²+21² = x²
841= x²
x= 29
nearest tenth = 30
-3y +12 = -48
-3y = -60
y = -60/-3
y = 20
A. The magnitudes are 10, and the direction angles are about 18 degrees.
