<h3>Right angle triangle:</h3>
- A right angle triangle has one of its angle as 90 degrees. The sides can be found using trigonometric ratios.
Therefore,
sin 60° = opposite / hypotenuse
sin 60° = b / 500
cross multiply
b = 500 sin 60°
b = 500 × 0.86602540378
b = 433.0127
b = 433 meters

So you have 20 people and 10 percent have brown eyes. So if 100% is 20, to find 10 percent you divide it by 10 to get 10% is 2. You know all the rest have hazel eyes so you just do 20-2 to get 18. Therefore 18 people have hazel eyes. Hope this helps :)
