Two fire-lookout stations are 190 miles apart, with station a directly south of station b. both stations spot a fire. the bearing of the fire from station a is upper n 55 degrees upper e and the bearing of the fire from station b is upper s 60 degrees e. how far, to the nearest tenth of a mile, is the fire from each lookout station?

If (x-2) 2= 49, then x could be a. -9 b. -7 c.- 2 d. 5 e.9

The function models the number of accidents
