A biologist wants to know the width w of a river in order to set instruments to study the pollutants in the water. From point A, the biologist walks downstream x = 98 feet and sights to point C. From this sighting it is determined that 6 = 50 (see figure). How wide is the river? STEP 1: Use trigonometric relations in the right triangle (see gure) to find the numerical relationship between w, x, and 9. tan(9) = STEP 2: Solve for w. w = ( Q) ~ ran STEP 3: Calculate w. (Round your answer to two decimal places.) w= ft
