Question

The answer with steps please​

Answer 1

Answer:

width of river = 130m approx

Step-by-step explanation:

angle is 60°

length of bridge 150m

this becomes the hypotenuse

let the width of river be x becomes it's opposite side

by using trigonometry value

sin 60° = √3/2

$\frac{ \sqrt{3} }{2} = \frac{x}{150} \\ x = \frac{150 \sqrt{3} }{2} \\ x = 75 \sqrt{3} \\ x = 75 \times 1.732 \\ x = 129.9m$
