$c \approx 600$ mile $a \approx 416$ mile $b \approx 431$ mile
1. Find the inertial angle of A by subtracting the external degrees from 180: $\angle A = 180^{\circ} -84^{\circ} - 52^{\circ} = 44^{\circ}$ 2. Find the distance of c by multiplying the speed by time $c = 250 mph \times 2.4 h = 600$ miles 3. Use sine rule to find a $\sin 44^{\circ} = \frac{a}{600}$ $a\approx 416$ miles 4. Use cosine rule to find b $\cos 44^{\circ} = \frac{b}{600}$ $b\approx 431$ miles
