The measure of an angle is eight times the measure of its complementary angle. What is the measure of each angle?

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

3 times as much as the sum of \( \frac{3}{4} \) and \( \frac{2}{4} \)

10. Jika \( g(x)=x+3 \) dan \( (f \circ g)(x)=x^{2}-4 \), maka \( f(x) \) adalah \( \begin{array}{l}\text { A. } \\ \text { B. } x^{2}-1 \\ \text { C. } x^{2}-6 x-5 \\ \text { D. } x^{2}-6 x+5 \\ \text { E. } x^{2}+6 x+5\end{array} \)

Solve for \( z \) \[ \begin{array}{l}3 z=24 \\ z=\square\end{array} \]
