A boat heads out from point A on one island toward point D on another. The boat encounters a storm at B. 12 miles east and 4 miles north of it’s starting point. The storm pushes the boat off course to point C, as shown

i think the answer is .36

step-by-step explanation:

what i did was only 2.88 divided by 8

60

step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
