To divide complex numbers in polar form, divide the r parts and subtract the angle parts. Or
<span><span><span><span>r2</span><span>(<span>cos<span>θ2 </span>+ i</span> sin<span>θ2</span>) / </span></span><span><span>r1</span><span>(<span>cos<span>θ1 </span>+ i</span> sin<span>θ1</span>)</span></span></span></span> <span>= <span><span><span>r2/</span><span>r1</span></span></span><span>(cos(<span><span>θ2</span>−<span>θ1) </span></span>+ i sin(<span><span>θ2</span>−θ1)</span><span>)
</span></span></span>

= 3/7 (cos(π/8-π/9) + i sin(π/8 - π/9))
= 3/7 (cos(π/72) + i sin(π/72))
Answer:
94.6
Step-by-step explanation:
100% of 44 = 44
⇒ 200% of 44 = 44 + 44 = 88
15% = 15/100 = 0.15
⇒ 15% of 44 = 0.15 x 44 = 6.6
Therefore, 215% of 44 = 88 + 6.6 = 94.6
The answer is 52.
20+52=72
