Answer:
a ≈ 1.8
Step-by-step explanation:
a / sin (180 - 105 - 15)° = 2 /sin 105°
a = (2 /sin 105°) x sin 60°
a = (2 / 0.97) x 0.87
a = 1.79 (≈ 1.8)
The pick up fee is $2.50.
After each mile, $1.95 is added.

Isaac total charge = $27.46;
Generally, let the number of miles driven by the taxi be x, then we have;

Solving for the number of miles Isaac travelled, we have;
