Answer:

t = 6 hours

Step-by-step explanation:

First, we need to plug in our known information into d = rt.

450mi = $\frac{75mi}{1hr}$ * t

450mi = 75mi * t --- simplify fraction

t = $\frac{450}{75}$

t = 6 hours

$\tan(\Theta) = \dfrac{\text{opp}}{\text{adj}}$

$\tan(43) = \dfrac{x}{12}$

$x = \tan(43) \times 12$

$x = 11.2$
