Did I do this right?
The shorter leg of a 30° 60° 90° right triangle is 7.5 inches. How long is the longer leg and the hypotenuse?
1) The longer side:
7.5/Sin 60 =b/Sin 30
4.208723391 inches
Hypotneuse:
8.6 inches

bobpursley,
ARRRRRGGGGGG.
The shorter leg is opposite the smallest angle.
7.5/sin30=longerleg/sin60
Then redo the hypotenuse.

Lena,
Oops :O
Thanks 
Math 
Trig,
THE SIDES ON A 306090 TRIANGLE:
Short Side = x
Long Side = sqrt(3)*x
Hypotenuse = 2x
In this case:
Short Side = 7.5
Long Side = sqrt(3)*7.5
Hypotenuse = 2*7.5 
Math 
Lena,
Thanks :)
