Step-by-step explanation:
x = 144 ( corresponding angle)
y = 180- 144 ( linear pair)
y= 36°

Both same unit so multiply your numbers to get a great digits
Answer:
14080 ft
Step-by-step explanation:
You want to convert 4 mph to ft/min and then mult. the result by 40 minutes:
4 mph 5280 ft 1 hr
---------- * --------------- * ------------- = 352 ft/min
1 1 mile 60 min
Now multiply this rate (speed) by 40 minutes:
352 ft 40 min
---------- * ------------ = 14080 ft (answer)
min 1
This would be the same as 2 2/3 miles (in 40 min)
Sec(theta) = 1.3591392 => cos(theta) = 1 / 1.3591392 = 0.7357598103
=> theta = arccos (0.7357598103) = 0.744 rad = 42.6285 degress
