2. What's Mary's B It's 36 Oak Street.

1. \( y=2-4 x^{2} \)

\( \angle 1 \) and \( \angle 2 \) are supplementary angles. Given the measure of \( \angle 1 \), find \( m \angle 2 \). \( \begin{array}{lll}\text { 9. } m \angle 1=52^{\circ}, m \angle 2= & \text { 10. } m \angle 1=76^{\circ}, m \angle 2= & \text { 11. } m \angle 1=19^{\circ}, m \angle 2=\end{array} \)

Given: \( m \angle A=(4 x-2)^{\circ} \) and \( m \angle B=(11 x+17)^{\circ} \) 23. Find \( x \) if the angles are complementary. \( \quad \) 24. Find \( x \) if the angles are supplementary.
