11. Graphing Complex Numbers / Products and Quotients of Complex Numbers / Problem 6

Multiply the following complex numbers and express the final answer in polar form.
z₁ = 9(cos 35° + i sin 35°)
z₂ = 7(cos 65° + i sin 65°)

63(cos 30° + i sin 30°)

63(cos 100° + i sin 100°)

16(cos 30° + i sin 30°)

16(cos 100° + i sin 100°)
