1053 feet
Explanation of Solution
Given:
The highest bridge in the world is the bridge over the Royal Gorge of the Arkansas River in Colorado. Sightings to the same point at water level directly under the bridge are taken from each side of the 880–foot–long bridge, as indicated in the figure. How high is the bridge?
Formula used:
Calculation:
So from the triangle
Lets say distance is feet so the value of will be () feet(we know that the distance from to is 880 feet totally
–––––equation 1
From the triangle
–––––equation 2
From equation 1 and 2
So
So now
so the height of the bridge is 1053 feet
