A railroad bridge in one city has a low clearance for trucks. An engineer standing 25 ft away measures a 15.2 degree angle of elevation from her eye level of 5.8 ft To the bottom of the bridge. If the road is flat between the engineer and the bridge how high over the roadway is the bottom of the bridge?

answer: (1,3) (3,-1) (5,-5) ?

step-by-step explanation:

answer: the correct option is d.

explanation:

it is given that the triangle j'k'l' shown on the grid below is a dilation of triangle jkl using the origin as the center of dilation.

from the given graph it is noticed that k(4,8) and k'(2,4). let origin is defined by o and scale factor is defined by k, then

    (1)

distance formula,

put these values in equation (1).

therefore scale factor is     and option d is correct.
