Question

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



Short = 2

Long =

Answer 1

For this case what you should do is use the following trigonometric relationship:
 tan (x) = C.O / C.A
 Where
 x: angle
 C.O: opposite leg
 C.A: adjoining catheto
 Substituting the values we have:
 tan (60) = long / short
 tan (60) = long / 2
 long = 2 * tan (60)
 long = 3.46
 Answer: 
 long = 3.46

Answer 2

Answer:

2 times square root of 3
