Answer 1

A surveyor needs to determine the distance between two points that lie on opposite banks of a river. Along one bank, 300 yards are measured. The angles from each end of this line segment to a point on the opposite bank are 62° and 53°. Find the distance between A and B to the nearest foot.

Answer 2

so we trying to find c?

Answer 3

yeap side "c", yes

Answer 4

well first we can get B by doing 180-62-53

Answer 5

B=65 degrees

Answer 6

\(\bf \cfrac{sin(B)}{b}=\cfrac{sin(C)}{c}\)
