The top of a dam has an angle of elevation of 1.1 radians from a point on a river. Measuring the angle of elevation to the top of the dam from a point 155 feet farther downriver is 0.7 radians; assume the two angle measurements are taken at the same elevation above sea level. How high is the dam? (Round your answer to the nearest whole number.)
