Answer:
x = 60°
Step-by-step explanation:
See picture below. When two parallel lines are cut by a transversal there are some special relationships.
I'll assume the question is: what's the volume?
It's two L×W×H rectangular prisms (aka boxes) put together
The bottom one is 2×3×4
The top one is 5×4×1
Volume = 2×3×4 + 5×4×1 = 24 + 20 = 44
Answer: 44 cubic feet
Equate the real and imaginary parts independently to find x and y.
Real part: -4=x, so x=-4
Imag. part yi=3i, so y=3
