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

short = 7

long = ?



Umm according to what I know       The ratio of the sides of a 30°-60°-90° triangle are:
short leg : long leg : hypotenuse
1 : √3 : 2
 if the short leg is 7, the long leg is √3 times that:

7√3 ≈ 12.12 inches 

put like terms together.orremember that the 45 becomes negative when moved to the other side.orthe minuses cancel out.
