Fill in the missing values to make the equations true. \[ \begin{array}{l}\text { (a) } \log _{2} 3+\log _{2} 5=\log _{2} \square \\ \text { (b) } \log _{5}\left\lfloor\frac{1}{2}-\log _{5} 7=\log _{5} \frac{2}{7}\right. \\ \text { (c) } \log _{5} \frac{1}{27}=-3 \log _{5} \square\end{array} \]

Which equation illustrates the identity property of multiplication? \( \begin{array}{l}(x+y i) \times z=(x z+y z i) \\ (x+y i) \times 0=0 \\ (x+y i) \times(z+w i)=(z+w i) \times(x+y i) \\ (x+y i) \times 1=(x+y i)\end{array} \)

An angle measures \( 82^{\circ} \) more than the measure of its supplementary angle. What is the measure of each angle? \[ \square^{\circ} \text { and } \square^{\circ} \]
