Question

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

Answer 1

ARRRRRGGGGGG.

The shorter leg is opposite the smallest angle.

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

Answer 2

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
