Answer:
C. 41.0, θ = 77.3°
Step-by-step explanation:
The sum is ...
5(8, 4) -3(-3, -4) +8(-5, 1) = (5·8-3(-3)+8(-5), 5·4-3(-4)+8·1)
= (40+9-40, 20+12+8) = (9, 40)
The magnitude is ...
√(9² +40²) = √1681 = 41
The angle is ...
arctan(40/9) ≈ 77.3°
The resultant magnitude and direction is 41∠77.3°.
Cubic volume=l³
l³= 1728
l= 12 feet
the aquarium is cubic shaped=> all l are equal
one side is a square with l= 12 feet
area= l²= l•l= 12•12= 144 feet²
