Question

*somewhat long*

imagine a 30-60-90 triangle

hypotenuse = unknown
shorter leg = unknown
longer leg = 10

so if the longest leg is 10, by the 30-60-90 rule the shortest leg is 10 divided by √3. So then for the shorter leg i got 10√3/2 or 10√3 over 2.

and now the hypotenuse is the shorter leg multiplied by two. so 10√3/2 x 2 = 20√3/3.

so for the hypotenuse i got 20√3 over 3.

can someone tell me what im doing wrong and show hows it done? please and thank you..im really stuck on this problem
