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

    ARRRRRGGGGGG.

    The shorter leg is opposite the smallest angle.

    7.5/sin30=longerleg/sin60
    Then redo the hypotenuse.

    Oops :O
    Thanks

    THE SIDES ON A 30-60-90 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

    Thanks :)
