Answer 1

trigonometry? right?

Answer 2

yes

Answer 3

to find the measure of the opposite side, given the measure of the hypotenuse and the central angle, use sin. . .

Answer 4

you're looking for the length of the side opposite to the angle (theta) so use the following trig identitiy:

sin(theta) = opposite/hypotenuse ----> opposite = hypotenuse*sin(theta)

SB = 785sin(41°) = 515 ft
NC = 834sin(46°) = 600 ft

600-515 = 85 ft
