Question

3) A bridge of length 600m is built across a river making 15 angle with the direction of flow. a) Draw a rough diagram b) What is the width of the river​

Answer 1

Answer:

Width = 579.56 m

Step-by-step explanation:

Since the bridge makes an angle or 15 degrees with the river bank, the triangle formed is an isosceles acute-angled triangle. The length of the bridge is the hypotenuse and = 600 m, so the width of the river is 600*cos 15 = 579.56 m.
