Answer:

Choice B. 6 km.

Step-by-step explanation:

We see this is a right triangle.

The height of this right triangle is 3 km and the angle adjacent to the height leg of the triangle is (90 - 26 ) degrees = 64 degrees.

We want the distance d which is the leg opposite 64 degrees.

tan 64 = d / 3 km ;

d = 3 * tan 64 = 3 * 2.0503038 km = 6.1509 km
