Abiologist wants to know the width w of a river in order to properly set instruments for studying the pollutants in the water. from point a, the biologist walks upstream 100 feet and sights to point c. from this sighting, it is determined that θ = 56° (see figure). how wide is the river? verify your result numerically. (round your answer to one decimal place.)

i got 10.28 but that rounds up to 10.3

in 1995, potato plants were taken into space aboard the space shuttle columbia.

step-by-step explanation:

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°
