Asw= 2
7:1=7 x1=7
7-7=0+3=3
The answer is +3
Given that
z₁ = 15 (cos(90°) + i sin(90°))
z₂ = 3 (cos(10°) + i sin(80°))
we get the quotient z₁/z₂ by dividing the moduli and subtracting the arguments:
z₁/z₂ = 15/3 (cos(90° - 10°) + i sin(90° - 10°))
z₁/z₂ = 5 (cos(80°) + i sin(80°))
so that z₁ is scaled by a factor of 1/3 and is rotated 10° clockwise.
Answer:
87°
Step-by-step explanation:
it can be seen directly
if you want angle AOD
it's 78°
The correct answer is 400 yrds
