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

The shorter leg is opposite the smallest angle.

7.5/sin30=longerleg/sin60

Then redo the hypotenuse.

**Trig**, Thursday, November 13, 2008 at 10:02pmTHE 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
