He sets his total station up near angle and measures both the angle to be 26.97 degrees and distance x to be 218. How wide is the river? Help Question 9 10 pts Ik- -56 AM Search Windows ^ 4 11/29/2017

Explanation / Answer

Here ,

theta = 26.97 degree

distance , x = 218 m

let the width of the river is y

tan(theta) = y/x

tan(26.97 degree) = y/218

solving for y

y = 110.9 m

the width of river is 110.9 m
