Question

3 points A sniper is sitting on top of a tower at a height of 60 ft. There are four work- ers K , L , M and N standing at a distance of 96 f t , 90 f t , 82 f t , and 75 f t respectively from the base of the tower. The heights of K , L , M , and N are 6 f t , 5.5 f t , 5.7 f t , and 5.2 f t respectively. The sniper misfires a bullet at an angle θ with the horizontal. Since the range covered by the bullet is short, the path of the bul- let is assumed to be a straight-line path. If t a n θ = 2 3 , choose the correct option.

Answer 1

Answer:

all workers are safe

Step-by-step explanation:

S(0,60)

N(75,0)

M(82,0)

L(90,0)

K(96,0)

given, tan θ =  2/3 i.e. slope(m) = 2/3 = 0.67

find the slope of SN, SM, SL, SK

m(SK) = 0.625

 Therefore SN,SM,SL,SK is inside the slope 2/3

                    THEREFORE all workers are safe
