Determine the factors of x2 - 12x - 20. O (x-2)(x + 10) O(x - 10)(x + 2) O (X - 5)(x+4) O Prime​

You have two angles,

A=32°20'

B=57°40'

so, angle F at the fire, is 90°

d/5 = cosA = .845

d = 4.2 mi

If angle F had not been 90°, then using the law of sines,

d/sinA = 5/sinF

for this problem, sinF = 1
