Well it says nearest meter, so just guesstimating it looks about 3701, D, but that's pretty much all I get.

Angle DAC = Angle ACB (alternate interior angle because AD and BC are parallel and the line or transversal AC cuts them.) Therefore angle C = 7 degrees. We want to find AB. We know BC to be 3,729 meters. What trig function connects AB and BC involving angle C?

ranga Group TitleBest ResponseYou've already chosen the best response.1
Yes. tan(C) = AB / BC AB = BC * tan(C) plug in the numbers and calculate AB.
