Question

the length of the hypotenuse of a 30-60-90 triangle is 22 meters find the length of the side opposite 30 degree angle

Answer 1

`This\ triangle\ is\ a\ half\ of\ equilateral\ triangle\ which\ sides\ are\ 22\ m.\\\ so:\\side\ opposite\ 30\ degree\ angle\ is\ height\ of\ this\ equilateral\ triangle:\\h= (a\sqrt3)/(2),\ where\ a=22\\h= (22\sqrt3)/(2)=11\sqrt3\\\\Length\ of\ the\ side\ opposite\ 30\ degrees\ is\ 11\sqrt3`
