Answer:
22 miles
Step-by-step explanation:
Given data
A towing company charges $50 plus $4 per mile
let the number of miles be x
the expression for the charges for x miles y is given as
y= 50+4x
for y= 138
138= 50+4x
138-50= 4x
88= 4x
x= 88/4
x= 22 miles
Hence the distance is 22 miles
Since the segments inside a parallelogram bisect each other, 16 = 2y - 4 and 40 = 2x + 6
x = 17
y = 10
Answer:
∠A=26º
∠B=137º
∠C=17º
Step-by-step explanation:
We can use the Law of Cosines because we have all 3 side lengths.
cosA =
cosA=28^2+12^2-18^2 / 2(28)(12)
cosA=604/672
cos-1(604/672
angle A ≈ 26º
cosB =
cosB=-316/432
cos-1(-316/432
angle B ≈ 137º
26+137=163
180-163=17
angle C ≈ 17º
