Question

Using the technique in the model above, find the missing sides in this 30°-60°-90° right triangle.



Hypotenuse = 12

Long =

Answer 1

For this case what you should do is use the following trigonometric relationship:
 sin (x) = C.O / h
 Where
 x: angle
 C.O: opposite leg
 h: hypotenuse
 Substituting the values we have:
 sin (60) = long / Hypotenuse
 sen (60) = long / 12
 long = 12 * sen (60)
 long = 10.39
 Answer:
 long = 10.39

Answer 2

6 square root(3)
