Find the measure of two supplementary angles, C and D, if C=6x-4 and D=4x+9
Anastaziya [24]

Answer:

x = 17.5 mm

Step-by-step explanation:

Supplementary means that two angles adds up to 180 degrees.

If C and D are supplementary, that means that they equal to 180 degrees.

Combine like terms:  6x - 4 + 4 + 4x + 9 - 9 = 180 + 4 - 9

10x / 10 = 175 / 10

x = 17.5

So, x = 17.5 mm

Find z 1 ÷ z 2 for z 1 = 9(cos225° + isin225°) and z 2 = 3(cos45° + isin45°).
olga nikolaevna [1]

\bf \qquad \textit{division of two complex numbers} \\\\ \cfrac{r_1[cos(\alpha)+isin(\alpha)]}{r_2[cos(\beta)+isin(\beta)]}\implies \cfrac{r_1}{r_2}[cos(\alpha - \beta)+isin(\alpha - \beta)] \\\\[-0.35em] \rule{34em}{0.25pt}

\bf \begin{cases} z1=9[cos(225^o)+i~sin(225^o)]\\\\ z2=3[cos(45^o)+i~sin(45^o)] \end{cases}\implies \cfrac{z1}{z2}\implies \cfrac{9[cos(225^o)+i~sin(225^o)]}{3[cos(45^o)+i~sin(45^o)]} \\\\\\ \cfrac{9}{3}[cos(225^o-45^o)+isin(225^o-45^o)]\implies 3[cos(180^o)+i~sin(180^o)] \\\\\\ 3[(-1)+i~(0)]\implies -3+0i
