Answer: B. 29 mi (which you typed 29 in)
Step-by-step explanation:
Use law of cosine to solve: a²=b²+c²-2bc·cosA (the corresponding angle)
a²=19²+12²-2×19×12×cos (138)
a²=361+144-456cos(138)
a²=505-456cos(138)
a²=843.874 (rounded)
a=29 mi

Step-by-step explanation:
It is always good to draw a picture to help you. In this case
tan F = 40/44
m∠F = arctan (40/44) = 42°
$80 x 0.18tip = $14.4 (tip)
$80 + $14.4 = $94.40
